assembling the new 289

Getting close to the end here. Want to know if there are any special things needed to do when assembling all, like installing the new head bolts on the ol 289. are there any that needs thread sealant or ???. Ive done SBCs but not a SBF. just checking all my ducks.

Re: assembling the new 289

Can't remember butt............
Did you chase ALL the threads with a bottom tap??
Were all the head bolt thread holes blind holes or did the tap go all the way through? IF they were all blind-as-Stevie-Wonder.(IF you really think he IS blind!) then no sealant is necessary. ARP recommends their special lube when torquing head bolts.
My 'home-made'/shade tree recommendation is....replace all the weird sized bolts on the front cover/water pump with studs/all-thread using anti-sneeze on them all. Sure simplifies assembly/dis-assembly if you ax me.
FoMoCo connecting rods are 'near-bullet-proof' IF.........you replace the rod bolts with ARP's  AND ...have the big ends re-sized. They should make many trips to 6000+ RPM's with this mod. (One less thing to worry about too)
Did you put a bigger cam in it?!  Delta Cams  is right-around-the-corner from you (Tacoma, Wash)...Jus say'in!
Always good to degree the cam...........just for the peace of mind that it is"right-on". Little more duration and a 'dab' more lift will make the 289+30 over "stand-up-and-be-counted"!! (Remember....smaller LSA increases the snotty-ness) jus say'in!!
Prolly work with you new/re-furbished  stock-like valve springs.
Did you zero-deck the block?!  Good way to bump up CR...(= more power)
Inside the exhaust ports..........there is a thermactic hump... easily ground down for better exhaust flow. Thank you Uncle Sam for your attempts at "pollution control"
You COULD port match the intake(and exhaust) ports on the head to the intake mani & exhaust headers BUTT-EYE...........have read where that is a waste of time  OR   a minor HP bumper upper. You make the call.....
Pay close attention to getting the thrust bearing clearance right. Worng and it could eat-up a crank AFTER everything is back together!!! ouch..... 
Get the rear main seal right too or yukkkk.
Don't forget the plasti-gage!!!
Standard pressure oil pump is fine  Melling is what I use BUTT.......'I -heard' they have a good and a better pump. Spring for the better.
Don't forget.....get the heavy-duty oil pump driveshaft. Make sure you get the retaining clips in the right place so IF you pull the distrib. it WON'T pull the driveshaft out of the oil pump and fall into the pan.......with the engine all assembled and back in the car!
Please tell me you have altered your timing curve in your distrib.!!!! very important
One final thought......Have you bought your new pistons yet? the reason I ask is.....the newer mm type rings are thinner but still offer good performance. Like the rings in new engines they have considerably less friction which means the crankshaft can spin with A LOT LESS effort. Less drag means freeing up more power!!!! Wish I had used them.
As a test.....hook up your torque wrench to the crank bolt and measure how much torque it takes to turn the engine over! Trust me.........itsa lot!

Re: assembling the new 289

No 289 block had head bolts in the water jacket. The early 302 didn't have any either but the later 5.0 did.

Re: assembling the new 289

Your crankshaft flywheel bolts will need sealant.  Also, be careful on the four corner  ends of the intake manifold as those bolts are not supported, so you can break those ears off.  But that is stock heads/manifold.

If multiple things can go wrong, the one that will go wrong will be the one that causes the most damage.

Re: assembling the new 289

Oh and the thrust hearing is NOT on the rear bearing like Chevys.  Make sure it goes on the proper cap.

Re: assembling the new 289

Be sure your timing chain upper sprocket matches the type of fuel pump eccentric you are using.

If you have an early style timing cover where the crank seal must be installed from the inside, you can grind off the flange around the hole and install the 80’s and later seal that has its own flange and installs from the outside.  You will appreciate this if a subsequent seal change is ever required.

Re: assembling the new 289

My advice is to just check everything.  Plastigauge isn't going to give you accurate bearing clearance measurements.  It typically reads tighter than actual.  I use it verify consistency of clearances and that there is clearance.  Check your crank and cam endplay.  I like to install the cam first so I can guide it in from underneath.  Then set the crank, and once everything is torqued put a 1/2" breaker bar on the end of the crank parallel to the floor and let it go.  It should spin freely to perpendicular.  If it doesn't something is too tight.

Check your rod side clearance.  If you are using a stock crank, rods, and bearings there's not much trickery to it.  With aftermarket parts the crank fillet radius needs to be paired with the bearing sides that are chamfered, and the rod sides that are chamfered or you can lock up the engine.

I always pull the oil pump apart and check clearances.  That said the Melling standard volume/pressure pumps have always been perfect out of the box. 

Degree the cam, but don't get absurd about it.  The equipment you will use is likely going to get you a measurement within 2 degrees.  If you get that and its repeatable, good enough.   would not mess with trying to change installed centerline unless something was WAY off.  2 degrees +/- from straight up is only going to move the powerband by 100RPM either way, and that's assuming your measuring tools are accurate enough (which they probably aren't).  Plus, there's a lot of hysteresis in the factory setup, so its going to move around a tiny bit even in a running engine due to all kinds of factors (flex, chain stretch, etc.).  The idea is to check it and verify that its close.  Don't get carried away and think its a NASCAR engine. 

I always check rocker geometry with an adjustable pushrod so I'm sure the length is right.  You want the contact pattern centered on the valve stem top as verified with engineer's blue (a Sharpie actually works okay in a pinch too).  Run it through at least four crank rotations, which is 2 valvetrain cycles. 

Beyond that, just pay close attention to everything, even tiny details.  Stuff is very easy to fix on an engine stand.  Its a Royal PITA with the engine in the car.

Re: assembling the new 289

Thanks everyone. I have the crank, cam and pistons in now and the timing gears and chain are covered up with water pump installed. Next its heads and valve train.

6sal6 I got to get you the cam specs

Re: assembling the new 289

So I must have gotten old when I retired and don't remember anything. I have messed up my assembly of my new 289, 3 times now. But they do say 3rd time is a charm. Im going for #4. I have never had such a bad, hard time doing a new motor. This one may never run. 
1st:   I used my old timing gear set because it only had 2K on it, but it was the wrong gear and sandwiched the cam plate between the ft of the cam and the back of the gear, not sure why we tested that but glad I did. Got new parts and fixed.
2nd: I broke a ring while installing on #7 piston waited 2 days for new set.
3rd:  I forgot to gap them and removed them to set gap, they were at .011 Day 3
4th:  While asleep last night I realized that I installed the trust bearing on the rear not #3. now waiting tell  Thursday for new thrust baring.  Thursday we will start all over and try to get it right. If not I will start drinking.

All in all I have replaced the rings, crank bearings and timing set and haven't turned the key once.

Re: assembling the new 289

Don't be too hard on yourself.  Its not like you build engines every day.  Two pieces of advice:

1.) Use ring expander to install the top and 2nd rings.
2.) Get a tapered bore ring compressor. 

Makes life so much easier.  Most modern rings can't be spiraled on; they will break.  If they don't break they will likely be stressed to where they will break in operation.  The coffee can ring compressor is much the same.  Its really easy to get a ring hung up trying to get the piston in the block.  This can cause the ring to break, but you might not know it.  A tapered compressor allows you to slide the pistons in using two fingers to push down on the top.  No mallet, no thumping.  Only downside is they only work for one bore size, but I've now built 3 engines with the 4.030 one I bought.

Re: assembling the new 289

Yeah.....I pushed a piston out of the hole and it hit the floor juuuuuust right and broke a ring. Machine shop I used just happened to have a set of rings for that very reason. They were nice enough to give me a ring so I didn't need to wait on a full set to come in the mail.
Another piece of advice that is 'universally' recommended is.....put some pieces of rubber tubing on the rod bolts to prevent scratching the cylinder wall when installing the piston/rod combo.
(Guess who didn't and what the results were!) yep....

Re: assembling the new 289

Absolutely, unless you've got those fancy, schmacy bolt caps that I got from somewhere.  ARP, maybe?  I think they say ARP on them.  Anyway, another reason to use capscrew rods

Serious question. What forces are involved that makes a bolt a better fastener for a rod than a nut on a stud?

Money I think.

Re: assembling the new 289

For one thing, you cannot put cap screws in just ANY rod.

Re: assembling the new 289

As far as studs go though, there is one issue I can think of; there are two potential points that can loosen instead of one.  With a pressed in bolt or capscrew there is only one.  Rod bolts literally have the hardest job in the engine.  They are stretched constantly.  You can't put a capscrew in an ordinary rod, but they are one of the benefits of an aftermarket rod.

Re: assembling the new 289

Well if it can happen it will. Wrong valves has set me back again tell next week, guess I will just work on the railroad. This is just one of my latest. It is cement truck, 3" long ( HO scale 1/87th) I cut it apart and installed a micro motor to make the drum spin, and the frame flexes just like a real one when they are mixing.

Re: assembling the new 289

New motor is assembled now after pulling a stud out during the zero lash adjustment. Really?  that shouldn't of happed but glad it did now before I started it up. Shop gave me new screw ins for free. Tomorrow we install the new life into the olé gal. This has been a very long 3 months. Just a simple rebuild with a little more compression, ported heads, cam, headers, intake and a 4 barrel. Should run like it was meant too. The car is all new now less paint and I want to drive it so we will leave the paint as is from 1987 when ford repainted it.
