Are FE's worth the extra money?

     Here's the situation. Due to some personal issues I haven't done much in the garage in the last 2 or 3 years. I've  decided to shake my head clear and move on. Mustang need some lights wired and a little interior to get on the road. Fairlane body is done and I'm ready to start on the motor. So here's my situation.
     I bought a 66 Fairlane that I was told was a drag cag since 1968. The car floors still have the original paint inside. You won't find a 66 in PA cleaner than this one. There was interior metal cut out of the car to lighten it up. Someone took metal from another car and brazed it back in. My buddy and I ground out the braze and welded everything back together. I got a lot of extra parts and new interior when I bought this. I was told the motor, (390) was rebuilt by a very good mechanic. They wanted an extra $1000 for the motor. I paid asking price for the car and all the extras but they had to throw in the 390, I had no way to tell if it was good or not.
     So here's what i got. I got a 390 that may have been rebuilt. (Being this was done from drag guys I believe it was built but I don't know to what extent). My first thought was to use this for the Fairlane but now I'm thinking about putting a car together that may not run right. I did already purchase a Quick Time bell housing for a FE block, the cultch and pressure plate and TKO600.

That's the back ground now my question, What would you do. Is an FE worth the extra money?

Should I take my 390, stroke it, buy some aluminum heads and go that direction or buy a 351 Windsor and do the same. All input is gold!!! Where is money best spent

 


If this forum can't fix it, it isn't broke.

Re: Are FE's worth the extra money?

A healthy windsor will bring a smile to your face fer sure......
A healthy FE will......bring about massive tightening in the lower pants area !!
Any question!??!

Re: Are FE's worth the extra money?

The E in FE is not for economical!!! The first question you need to answer for yourself is what do expect out of the motor……mild street build, 500 HP, enough torque to move a mountain, enough vacuum to operate power brakes?
 
Did any paperwork come with the motor? I would start with verifying what the PO said about it being rebuilt and pull the pan and heads. Verify the stroke from the crank ID. Has it been turned down?
 
If the bore is .030 over, you might be safe on cylinder wall thickness. If it’s .060 over, it needs to be sonic checked for certain. With core shift, wall thickness can be all over the place. I had a .060 over block showing less than .100 in two non-thrust wall areas, was told it might cause some overheating and good to go otherwise. Had a .030 block that could not go to .040 without making several cylinders too thin.
 
Have all the press in oil passage plugs been replaced with pipe plugs?
 
See what pistons are in it to determine the compression ratio and bore diameter. You don’t need a 12-1 motor for the street. Where do the pistons stop in the bore at top dead center? Flush with the deck, near flush, down .100 or more?  What heads do you have? The casting number will give a good idea on head CC. That car should have had a 14 bolt exhaust pattern. Bottom row center cylinders would not be drilled. Top row outer holes would be lower than center.
 
There are plenty of choices for aluminum heads with Edelbrock, Survival Motorsports, Bear Block Motors (BBM) and Trick Flow. Stay away from the cheap knock off stuff. Weigh the cost of these against how much $$$ it would take to correct any issues yours might have.   
 
What cam is in it now? Hydraulic, solid, number on the end? Does it have end support stands for the rocker arms? Check the dimensions on the rocker arms and rocker shafts to see if they are within tolerance….. it’s a great place to bleed off oil pressure.
 
Headers will be expensive. Ford Powertrain Applications makes a set that will fit well. I hear good things about REF headers as well. Buy the 5/16 hex head ARP header bolts (3/8x16 thread) and a ratchet wrench to make bolting them in easier.
 
Is the clutch linkage going to be mechanical or hydraulic? The quick time bell has the opening in a lower clock position than a Ford bell housing. It could make things a little out of alignment for mechanical linkage. Buy alignment pins from the link, very easy to install and adjust as you fine tune the alignment.

If all this checks out good, keep the FE knowing it won’t be cheap. If parts are not checking out, then a Windsor will most defiantly be cheaper to build.
 
I like the FE motors and will justify the extra dollars to myself to get it built.

Re: Are FE's worth the extra money?

My friend has a 390 in his 64 T-bird that he uses for summer time cruising and to tow his small vintage boat.

When he decided to have engine rebuilt several years ago, he asked me about the camshaft I was using in the 289.  I suggested the Edelbrock Performer camshaft designed for idle-5500 rpm.

He’s always driven responsible...as long as I have known him.  He discussed camshaft options with his engine builder and for his use suggested the same camshaft.

He’s been very satisfied with it.  He drives the T-bird more especially for long trips out of state too.
I get a kick seeing him drive it every summer...he likes taking the boat out more too.

He only did camshaft and lifters, he kept stock intake manifold on the car.
Sounds nice too.

That’s about my only experience with FE’s.

Edit: correction...my dad had a 390 in a 77(?) pick up that kept burning up valves.
Around the time unleaded fuels were introduced.

Re: Are FE's worth the extra money?

From a pure cost standpoint, you can probably build two stroker small blocks for the cost of a stroker FE.  Once you get into aftermarket heads the power advantage the FE has over a SBF pretty much goes out the window. 

That said, we don't really do this hobby using cost alone to make our decisions.  In fact, cost is usually pretty low on the list provided we can actually afford either option. 

If you can afford to spend $12,000-$14,000 on the engine then I would build a 445 stroker from the 390 using Survival modified Edelbrock Performer RPM heads.  Such an engine will make an easy 500HP and still be a very tractable engine in terms of idle quality, vacuum, etc.

By contrast, you can build a stroked Windsor for $6,000-$7,000 that will make less torque than the FE, but the same power (you're going to wind it a bit higher to do that, but nothing crazy).

My thoughts are that everyone has a stroker small block.  Hell, I've got 3.  I've also got a 390 under one of my workbenches for the day when I finally decide that I've had enough of everyone having a stroked Windsor and finally build my own 445.  If the car is already set up for the FE you're ahead of where I was starting, and part of my decision had to do with everything around the engine I'd need to change.  You would have to spend a decent chunk of change to go to a Windsor, so the cost disparity is probably not as great as my initial quotes.

Re: Are FE's worth the extra money?

If the engine is complete and needs nothing why not throw it in and start it up. Then evaluate it from there? We all like spending other people's money, , but in this case I'd at least give it a whirl before moving on to other options. My bet is that it will be super fun with the 5 spd.

Re: Are FE's worth the extra money?

I've only had one FE and that was in the car I married. 66 Galaxie 500XL with 390. Nice car. Fast car. developed a valve tick that drove me nuts! Only fix was new bigger cam. Found one that would wake up the mid range without needing a lot of valve work. valve tick fixed with a plus!! That was during college days and newly married so budget was thin. After market cam was cheaper than Ford so it was a sell. Real nice running car after that!

I wish it was that easy, that was my original thought but I'm a guy and we always want to go bigger. I think I'm going to stay with the FE. This is all I know right now, Edelbrock performer aluminum intake, D2TEAA heads  and was told it was rebuilt by a good mechanic. I think right now I need to listen to Bolted and take the heads and pan off and see what I got. All though I've done mechanic work growing up, I was more of a body guy. I know a very good machinist but he isn't a Ford guy. I'd like some help once I find out about the block to put all the pieces together. I'm thinking a 445 stroker as TKO suggested, good aluminum heads and roller cam. I want it to be streetable but I think Mike and I have the same CAM gene, I want the car to shake a little too. I've never built a motor so any help will be appreciated.

Re: Are FE's worth the extra money?

here's a good 'cam' idea!
Do some research and find out the specs on the LeMans cam for the 427. Duration and LSA especially.
Now the Le Mans (or which ever) is Old Tech: meaning the modern cam grinder can make A LOT more power OR....more streetable grinds than the old 60's stuff.
Once you find out these specs.....they will be for solid lifters. A roller can easily handle those kind of duration/lift/LSA numbers.
Soooooooooo if you get a roller with about the same duration and LSA with maybe less lift numbers (easier on the springs...this is a street cam we're grinding!)...I bet you will be looking at a healthy roller cam that would perform well on the street!!!
Call Delta......Howard.....Lunati...and  TELL THEM what you have in mind and see what they recommend.
I'm a big believer if you go into a conversation with some grind specs in mind....they will be more apt to talk to you .....instead of sell you something just to get you off the phone!
Sure they want to help but......time is money and if they can sell you their standard "Chevy grind" that fits evrything......they made a sale, now I can go get some coffee.
That's one reason I like the guys at Delta Cams...........they make you feel like you are their only customer and they will be going for a ride with you when you finish your build!!
Tell'em you want it snotty....or not!  Ken (at Delta) told me 90% of the guys they custom grind for say..."it's a street rod but I want it to lope and cut-up like a race car!!" 
They can give you BOTH!! (they did for me!)
I'll help you if you like!?
Heck......we all will!!!

Re: Are FE's worth the extra money?

The issue with an FE with a hydraulic cam was that the rockers were non adjustable.  The benefit of the shaft rockers was that you just bolt them on and go.  The disadvantage of the shaft rockers is that you just bolt them on and go.  If something is a little bit off there's not much you can do.  My advice would be to pony up for aftermarket roller rockers that are adjustable.  Adding the end stands to prevent shaft failure is also a good idea.

Re: Are FE's worth the extra money?

I have a '66 Fairlane with an FE, so I'm biased, but:

1.) The FE is what the Fairlane was born with.
2.) You already have a 390 and other parts

I'd be inclined to go through the 390 and verify what you have. If you have the regular  Edelbrock Performer, I'd trade up to the Pefromer RPM. The straight up Performer is considered Low performance by the FE crowd. Adjustable rockers are nice, unless you have a super-duper machinist who can set up the valve stem heights "just so" so that the valvetrain all works like it's supposed to with the non-adjustables. You don't have to go with the full aftermarket roller rocker set-up. The original ford style adjustable rockers are readily available as individual pieces or as complete assemblies with the shafts and stands. Depending on how radical a cam you choose, and how stiff the valvesprings are it might be good idea to use end stands and solid spacers on the rockers instead of the springs that are usually used to separate the rockers on the shafts. Not sure where that places you cost-wise relative to a complete roller rocker set-up though.

If horsepower per dollar is the deciding factor, Then I agree with others that the Windsor based platform wins, but maybe not by as much as has been stated.

My cost analysis on the FE rockers led me to the conclusion that it was very close to a wash to just use new parts rather than try to run half old, half new.  You also get the benefit of rollerized rockers as opposed to non roller to reduce friction and increase power. 

HP per dollar is all based on how much power are we talking about?  At 350HP I'll bet the engine you have is already close to that, so the FE wins.  At 400HP you're going to need a better intake, head work, and cam.  Probably still in the FE's favor if you stick with iron heads due to the cost of aluminum FE heads.  If you step up to aluminum heads I would target 500HP and it tips in favor of the Windsor, BUT that's engine cost alone.  This does not factor in bellhousing, engine mounts, etc. 

I think you are still bucks ahead with the FE if its remains a 390, though any 500HP engine is going to be somewhat rowdy unless its huge, so a stroker starts to look like a better street engine, and that's where the Windosr beats the FE because of how common Windsor strokers are.  Engine for engine you can build a 427 Windsor for less than a 445 FE and the engines make the same power, though the FE has more low end torque and will idle smoother. 

I still say, cool as a 427 Windsor is its still a Windsor stroker.  Plenty of guys have them.  The 445 FE still pins the cool factor and the "I've NEVER seen one of those!" factor.

Gotcha, if the engine is on a stand you could simply flip it upside down and can probably see the piston part numbers. But I totally understand wanting to take it apart to learn and positively identify everything.

You have to be careful using part numbers and casting numbers on FEs, because Ford often used the same parts in numerous configurations.  The 390 for example has the same bore as the 360 and 391FT engines.  I once thought I had a 428 someone had swapped into a truck in place of a 390.  Nope, 428s and 390s just use the same crank casting that were then machined to different stroke lengths.  Since they lack a part number stamping there's almost no way to tell them apart, except measuring or decrypting surrounding parts.  FE's can be hard to identify, and with money at stake in making mundane examples appear high performance I'm always careful and skeptical when FEs are being identified.  I think all but the SR blocks have 352 cast in the front of them regardless of displacement.  Is it a 352 or 390 someone added cross bolted caps to so they can claim its a 427?  Is it actually a 406, some of which also had cross bolted mains?  A good buddy had a mud bog race truck that ran great with what we thought was a 390, turned out it was actually just a 352.  He never knew until he went to freshen it up at the end of one season and the machine shop told him the bore was too small to be a 390.  It worked so good that he freshened it up and threw it right back in.  The shorter stroke I think made it wind better and mud racing loves torque, but it loves RPM more.  Anyway, thanks for making me think of that, I have many good memories of monkeying around in his shop when we were younger and had free time.

Re: Are FE's worth the extra money?

Glad to see you are going to open it up and take a look, it will go far in getting the motor right for you.
 
D2 heads are the go to TRUCK head. Something to watch for when it comes to factory or aftermarket heads is the exhaust port floor. D2’s and the C7AE-H will match and work well with a header flange for a 390 GT head or what was typical for a Fairlane 390 motor. The Cobra Jet, C80E heads have a different elevation on the port floor and I think the C6AE-R matches it. So… all that to say be very careful when you go to but headers, the mismatch with the port could have you chasing exhaust leaks from now on. Whether you have bigger valves installed in the D2’s or buy aftermarket heads, you will also need to watch the valve sizing and your cylinder bore. Too big of a valve could cause contact with the cylinder wall. When I bought Barry’s heads from Survival, he set them up with valve springs good for a hydraulic roller good to .600 lift. I don’t know anything about Edelbrock’s or the BBM’s. With the TFS heads, they may need some milling on the flats for the rocker shaft stands get the geometry correct. Know what you want when it comes time to order. Pick your heads then pick your headers.
 
You can wander through the broccoli patch with rocker arms. To me…where a steel rocker arms rides on a steel shaft there will have more friction at that point than on the tip of the valve where the rocker arms rides on it. If you find a rocker arm with needle bearings for the shaft, something got reduced to make up for the extra bearing. A smaller shaft may or may not have issues. Reduced material in the rocker body could lead to failures. I have factory steel non adjustable that were resized from Rocker Shafts Unlimited in California. They were resized with bronze bushings on oversized shafts and cost me more than the new cheapies you can get from Summit or Jegs. End stands from Precision Oil Pumps are a great buy. He was also cheaper than the speed shops for the rocker shaft stand studs. I kept the springs and added the shims to make sure the rocker arms were aligned over the rocker tip.
 
It doesn’t matter if you buy adjustable or non adjustable rockers, if you go with a roller cam, which I highly recommend, you will need new pushrods. The Morel hydraulic roller lifters have a good name for longevity with the FE crowd. They also came with a 5/16” cup. My ball on ball pushrods came in around 8.5” with a 5/16 ball and 3/8 ball from Smith Brothers. They are not that hard to measure. I borrowed a 12” dial caliper for the first set and bought one from Amazon for the second set. It wasn’t that expensive. If you are measuring pushrods for adjustable rocker arms, make sure the adjuster screw is showing no more than about 3 threads. Fewer threads can cause the cup on the pushrod contact the rocker arm body.
 
I will second the RPM Performer for an intake upgrade. I got mine second hand for $325 plus the ride from a forum member on Jay Browns FE Forum.
 
The crank should have a stamp on it somewhere toward the center to indicate the stroke, something like a 1U, 2U, 3U. The 390 and 427 will have the same stroke, the 428 is different. Some of the 427 cranks had a $ stamped on them. For the block, the cylinder bore is the best way to make a determination. The 352 and mirrored 105 on the front of the block are typical for different casting foundries, I think. I’ve read stories about 390 blocks that could be bored safely to a 428. Blocks cast as side oilers and drilled for center oilers…there is no telling to what you may find.
 
When it comes to break in time. I would suggest a day on the dyno or build a stand on your drive way and run it…. for a while. Make sure it isn’t leaking oil, hot idle oil pressure is good, not making any funny noises, and whatever else you might think of. It will be a lot easier to do out of the car versus in the car.
 
 
I wasn’t worried about the car shaking from the cam, I was more interested in enough vacuum for power brakes. A good cam could net you with better manners, HP, and torque without causing the rain drops to dance across the hood. The right mufflers could make that happen. Brent Lykins helped me with cam selection to work with my combo of parts and what I wanted in the end. My custom Comp Cams hydraulic roller and Morel lifter was around $900.

Re: Are FE's worth the extra money?

"Rowdy".........I like that!
Going with FoMoCo adjustable rockers instead of the 'high-end.bells & whistles;eye candy-wallet lightening-race only-build budget over kill could be a good economy move.
X-2 on replacing the Performer with the Performer RPM. Selling the Performer will be NO PROB because ALL FE guys are wanting a lighter intake!! (that puppy weighs A LOT....like 50lb +!!!)
Check with the guys you bought it from to see if they have a good used 428 crank and assembly......might save a few coins that way too. Not sure what the cu. in. would be with a 390 and a 428 crank. (411?)
Now.......converting over to a roller set up might be a little pricey though.
Ehhhh.....just-pictures-of-dead-presidents, right?!!

Re: Are FE's worth the extra money?

An iron FE intake weighs close to 100lbs.  The first one I took off I pulled all the bolts, broke it loose front and rear from the gaskets and tried to yank it off with a couple fingers inside the carb hole.  I thought I missed a bolt or something.  I couldn't believe how heavy it was.

On rockers, there's merits to both schools of thought, but the idea that an aftermarket rocker is going to fail over a stock one seems unlikely for two reasons.  First, how much are you really going to drive it?  If the life of the rockers is 100k that's going to serve most guys their life with the car and well beyond.  I remember guys talking about the life expectancy of Crane roller rockers for the 5.0, because they were aluminum.  Lots of guys said they would wear out.  Well, my buddy has a '95 Cobra with over 200k on a set of those rockers.  The engine underneath them has been rebuilt 3 times.  Each time the rockers passed every test thrown at them.

Second, aftermarket parts (I'm talking about real deal good parts, not eBay made in China crap) are built with racing in mind.  Guys that are pushing their cars to the max, where 5HP is a major advantage, etc.  Thinner sections, etc. don't necessarily mean they are weaker.  It all comes down to material selection.  How a rocker is loaded can also make a difference.  When you point load a stamped rocker on the shaft its loaded at that same point every time.  When you do that with a roller rocker the roller isn't loaded in the same spot every time because it rotates in operation.

My thoughts, FE rockers are expensive no matter what you do other than just slapping the stock stuff on and hoping for the best.  The shaft rockers almost no matter how they are set up is a major advantage over stud mounted rockers in terms of high RPM stability.  All that said, you are building a high performance engine in the modern era.  I personally won't build an engine without a roller cam and roller rockers.  Every engine built today by the OEMs that still use pushrods has a full roller valve train from the factory. 

That said, part of the reason I decided not to built the 390 I have is that the cost to build it the way I wanted was a lot more than the 347 I got for a screaming deal.  My thoughts have always been that I simply don't compromise.  If I can't do it the way I want now; I'll just wait.  BUT, its a different story when  you're trying to get a running car together, and at times I wander from that resolve in the interest of getting something on the road.  I always plan to go back to it later, but usually if it works I've become smart enough to leave well enough alone.  Temporary fixes have a habit of becoming permanent.  I read that in an old David Frieburger article in Car Car years ago.  Its in my top 5 of truer words were never spoken about the car hobby.

Walt, I don't know anyone with a FE that wishes they had a Windsor. Myself included.

     I guess that answered my question. ​A lot of good advice that I will be falling back on. My original though was to get new plugs and wires, rebuild the carb and see what I got. It's been hectic around here the last few years, work, help raising grand kids, Brenda's mom was living with us and my moms bad health. I just pretty much walked away from everything. I'm starting to get the itch back to get in the garage again. Haven't spent any real money the last few years so I just thought I'd go for a total rebuild.
     I talked with Barry from Survival Motorsports, he was kind enough to spend some time with me and answer some questions. As Kevin and a few others said, he told me to sell the Performer and get a Performer RPM intake. I'll be looking into his heads although he said supply is tight but I'm not in a rush right now. 445 stroker with a roller cam. All quality, no ebay parts. Some good thoughts on the rockers that I'll look into. I'll get some pics when I tear it down, hopefully this weekend.

Re: Are FE's worth the extra money?

Started to tear down the motor today and took a few pics. Looks to be a rebuilt 309 30 over and standard stroke.
