Mustang 65 inline 6 with 250 engine

Hello everyone I need your knowledge and advice to see if I can make this work.

Here is the my question, I have a 250 4.1L engine in a 1965 mustang coupe that originally was a 200, when I bought the car the 250 engine it was already there so I decided to keep it but I have the hood clearance problem since is using the original mounts and brackets, researching on the internet I read that the proper solution is to use a Maverick 250ci mounts and brackets but I have no idea how are these Maverick's brakets and mounts, which year?, where to buy? I couldn't find it and I don't know how they look like, is anyone there that already done this before? Any advice/help/pictures it would be more than welcome.

Thanks,

My application:
Mustang coupe 65
Engine 250 4.1L
Transmission: Manual 3 speed

There is a company called Prothane that makes engine mounts among other things.  Try them.
prothane.com/
Also Mustangs Plus Has lots of experience with such engine swaps.

Re: Mustang 65 inline 6 with 250 engine

I have a 250 in mine. I modified the 200 motor mounts if I remember correctly from roughly 1992. I elongated mounting holes to get it to fit in there.  You can't go too low but it'll work barely. The nice thing about that engine is the small block transmission mounting pattern on the block. It makes a T-5 that much easier with which to replace that 3 speed.


'66 Fastback since July 27, 1981. Springtime Yellow, originally a 200 cu in, 4 speed. Also a '92 LX Coupe, 5.0, 5 speed.

Re: Mustang 65 inline 6 with 250 engine

Years ago I had a 250 in my 68. I tried to make it fit with the Maverick mounts, but no go. I ended up getting the mounts from a 69 that had a 250 in it. I don't know if they would work in your 65, as it is two inches narrower than the 68.Good luck.

And...since nobody else has mentioned it....welcome to the best place on the web.  Hope you get what you need and stick around for a long time to come.  Oh, and don't be shy about coming to the Bash in June.  You'll be glad you did.

Sorry...I don't know nutin' 'bout motor mounts for no sik'silender.  Butt (TS&T), I'm one of those weird ones who just grabs some cardboard, steel plate, cuttin' torch, and the welder and makes it happen.  If that's not your forte yet keep in mind that M-mounts are fairly simple and you'll not learn any younger on anything easier, IMO.

Re: Mustang 65 inline 6 with 250 engine

I used frame mounts from a 70 Mustang coupe to install a 250 into a 65 coupe once. Everything fit perfect.

Re: Mustang 65 inline 6 with 250 engine

All of the above being said and given that I have been out of the loop for years, I would strongly encourage you to forget about the 250.  After all fitment questions have been addressed, you still have a six cylinder performance engine with V8 economy and a bit of extra weight.  In my book, it is a lose, lose , lose project.

You are very correct. Other than just having brag'in rights of a 6 cylinder Mustang with pretty good "pep".Just do the V-8 swap or just re-build what you have. IMHO too.

Guys, here we have a brand new member of the forum that ALREADY has a 250 in his Mustang that wants some help with motor mounts to lower the motor a bit. Telling the new guy his motor is no good is not helping.

Mustang Steve's recommendation of using the '69 Mustang six cylinder frame mounts has worked for some as has the 72 Maverick frame mounts.

I had a 65 Comet with a 250 that was a real good around town car due to the torque the 250 puts out. Mustang Steve had a 69 T5 (Mustang) that he put a five speed in and he said it was a good around town car. He sold that car because he had that blue 427 powered car in the garage.

Re: Mustang 65 inline 6 with 250 engine

Hornman is right.  I stand corrected about off subject advice.  My thinking at the time was that in the past it was very difficult to locate 1969-1970 6 cylinder motor support stuff.  That may have changed.  Everyone has differing ideas about projects they wish to pursue.  Having seen several of these cobbled up transplants in the past, I would personally not be tempted.  The stock 200 is good economy, and a small block is good power,however.  That should not discourage folks from giving it a shot for themselves, though.
Humbled,
Al
P.S.  I would really have been interested to see that motor in a 65 Comet.

Sorry to keep bringing up "usetawas's" but my old 4-Banger buddy, Wes Cooper got a sweet deal, way back in the 50's, on a nice Humber sedan with a bad engine.  So, being the recognized guru on all things Overhead Valve Converted Ford Model B, he built a Cragar OHV B and stuffed it in the Humber and drove is for quite a few years.

There was also a guy who hung out at Cooper's shop that put a Riley 4-Port B in a Pinto Hachback with a C-4 behind it.  He Built a custom oil pan so the engine could lay over enough to clear the hood.  On one of our Winfield trips to Las Vegas he got into a contest with a Porsche going up the Baker Grade.  With all that "B" torque he left that Porsch like it was tied to a tree.

OKay,  back to the present.

Hopefully we haven’t scared off the original poster.

Anyone have a pair of ’70 coupe frame mounts to offer him so he can resolve his hood clearance issue??

Re: Mustang 65 inline 6 with 250 engine

Hey guys, nop you have not scared me off actually I appreciate all the comments and tips, let me explain me a little bit more, I'm from Costa Rica and you can imagine that we don't have like a deposits, car graveyards or companies here that can build something specific or making a swap from 6 to v8 something affordable. I didn't contact yet the companies that lowercasesteve mention but the easiest way that I can read here is go for the 70 coupe frame mounts but I will need a little bit more extra information.

- I assuming the donate will be a 70 coupe with a 250 engine is that right?
- Are these frame mounts something that I can find in a common companies that sold aftermarket parts like "summit racing"?
- Is there any picture of those frames mounts to see how they look like?
- do you know a place like a graveyard that I can easy buy by internet?

once again I appreciate all your comments

69-70 coupe, fastback or convertible will work.  67-68 might work, but I am not sure about those.  These must be I-6 frame mounts, not V8 frame mounts.
These are not available new, only as pulled off a donor car. 
Ebay might be the easiest place to find some, or try Prestige Mustang near Atlanta Georgia.  They are the largest Mustang salvage yard in the USA.

Since you have a unique situation due to your location, the easiest thing to do might be to just fabricate the frame mounts.  Use the 69-70 rubber motor mounts, then remove your frame mounts with the engine supported from above.  Lower the engine to a more suitable height, then fabricate the frame mounts to connect your frame to your motor mounts.  Not rocket science and real easy to accomplish, especially on a six.  That would be a lot cheaper and easier than trying to find some.  Even if I had a pair right in front of me, I do not know if I could ID them for sure.

Re: Mustang 65 inline 6 with 250 engine

Can you take some pictures or measurements or ford part numbers of what you have installed? Maybe then we can compare that with what we may have.  I have a 6 cyl set off a 67.

Re: Mustang 65 inline 6 with 250 engine

Watching this - I'm working toward replacing my 351W with a 250 I-6.  Tired of "being the same", I want more room to work on stuff in the engine bay and I want to return the car to a more original state (it's a T code that a previous owner converted to V8 suspension, etc.). 

Just bought the engine from a 73 Maverick and have done some initial health checks on it (it needs some work but not sure what yet) but have not tried to fit it in the car yet.  I hope to do that tomorrow (or maybe later today).  It will have a T5z behind it.   Test fitting will let me see what I need to do for mounts - I hope.

I've read about the hood clearance issues and bought a Bronco air cleaner assembly on eBay that's offset and should not interfere with the stock hood.  There are also air cleaner horns for the older Jeeps on eBay that (with a little tubing and some modification) could be used to implement a remote air cleaner box.

I find it interesting that there is so little information out there about the 6 cylinders (even on fordsix.com).  It's a challenge and a great learning opportunity (hope I'm up to  it).

Re: Mustang 65 inline 6 with 250 engine

The reason there is so little information on the small Ford six is that stupid head design. The integral log intake does not breath well and cannot be made to breath even decently without major work. It is not really possible to make them breath "race well". The 250 heads are the best of a bad bunch. You can buy the new Classic Inlines head for $2000 or try to import a crossflow head from Austrailia. Then you run into the problem of getting a hot camshaft for it. After considering all these factors, most folks leave their small six stock and enjoy puttering around with it. After all, the 200 makes 85 HP at the rear wheels! That's plenty, right?

Well, that and the fact that everybody has to have that deep, throaty MORE POWER sound!!  :-)

It is for me!  I'm enough self-assured that I don't care what anyone else thinks about my stuff and I simply don't need (or want) mega horsepower - it just increases the probability of having collisions and getting tickets - both bad things.

Besides, if putting a 6-cylinder in a classic Mustang was easy everyone would be doing it, right?  :-)

Re: Mustang 65 inline 6 with 250 engine

You better be careful John! With that 0.62 overdrive in that T5, you're liable to get 35mpg in that car and the hairy chested Mustangers will really make fun of you.

Re: Mustang 65 inline 6 with 250 engine

The only reason there is a Ford bay in my garage today is that I took my drivers test in my Brothers (then new) 65 Mustang. It was a 6 cyl with a 4 speed from the factory. He had the dealer add the fog lights and it was one of the most fun cars I ever drove. Rangoon red with black interior. I used that car for the Proms and other events through high school. I also won a couple of Solo events with that thing, It was geared well and handled great. We bumped up the spring rate at all four corners and added sway bars. Finally did the Shelby drop and it was better yet.
