calling oldtimers!! need help with y block

I would like to talk to someone with a good running y block..
I have a 272 but want to find a 312.
I would like to know if the exhaust manifolds are the same, how far can you bore the block, what cam and where to get it, ect....
Thanks in advance!
Eddie

I had a 292.....way back in the day....it leaked real bad....( rope rear main seal ) It was in a 56 F100

Street Rodder Magazine did a very complete series of engine buildups for the Y block. It started in 1999......but I do not have the exact issues.....September was #7 in the series....

Maybe one of the other members can help.

I know that 312's have a larger crankshaft journal size and do not fit into a 272 or 292

h8louzn, Ive got those articles that Deuce mentioned, give me sometime and I will see if I can put them together for you. I also know someone here in town that deals in y- blocks, so I'll ask him your questions and see if we can get you some answers, just give me 3-4 days he's a hard guy to get sometimes.

Thanks for the quick response guy's!
I sold the 4.6 that was going to go in the 55.
Now I'm leaning toward the 272 that came out of it with dual quads or 3-2's.
I think I want to stick with the vintage look...
Thanks Again...
Eddie

The 312 is becoming hard to find. It also had weakness in the main web area. The trick is to find a good 292 and put the 312 crank in it. There are also available stroker kits. Use 57 heads.

We always heard that there were crank problems with the 312. There are a lot of good running 292s out there. You'll like it

From experience Do Not over rev your 292 you'll drop a valve. Ask me how I know? I didn't learn the first time LOL but you should have seen the look on the guys face in the firebird when I did it the second time just as I was grabbing third gear in my old 64 ford pick up! Some thing you might consider the FE will bolt right in uses the same motor mounts and tranny. I wish I had remembered that instead of putting the 289 in it.

Well back then my dad made the decisions, well at least for the pick up. My Mustang was another thing all together.

y block

have rebuilt many ys . have bored a 272 to 312 bore and used 312pistons 57 heads and rockers ran ver well,used 289 valv springswith the inner dampeners, very tough engines. 272 292 have a better rear seal. comes in overhaul gasket kit. only thing wrong with 312 crank in 272 292 is mains are largerwhich takes trick machineing as the seal aria must be turned down to acomidate the smaller seal. not aware of any one who has acually did this.the 312s have thin cyl walls as pretty much the same block as272, except for canadian built ind engines that had thicker cyle walls and forged cranks. stay with the yblock they are a good bet if built right. ps use the 57exmanifolds and intake
