The Stovebolt Site Forums The Shop Area Engine Shop Chevy 292 - are all the cranks the same?

OK. Making a long story short. I've got two 292 engines. Both runners; one (the original) out of my '64 C20. The other a "mystery" Mr. Goodwrench crate motor. I say "mystery" because I am unable to identify it's age by the casting number on it (another longish story).
Anyway. All the specs I have, or can get my hands on, indicate that since the 60's the motor went through many changes. The only change I'm interested in, is the crank. Reason being. The only reason I removed the original engine was because 1) It was newer and free, and 2) because the nose on the original crank was bent. Still ran and performed great. But ate harmonic balancers, and fan belts like candy.
So. Can anyone say with any authority that the crank was unchanged over the years? I'm strongly inclined to believe not. But would rather not build up my original, then decommission the truck dropping the crank out of it, and installing it in my old engine. Only to find it's different, and I need to wait for an order for a new one to arrive.

Thanks!

My Federal-Mogul shop specification manual lists the same dimensions and bearings for the 292 from 1963-89. That manual lists 12 different crankshaft forging numbers. Do you have access to the crank to check the number? PM me and I'll be glad to give you the numbers, or possibly I can scan and forward a copy of that manual page to you by email. I'm using the F-M specification catalog number 115, and there are usually copies of it available on Ebay for reasonable prices. It's got a wealth of good info, and it goes all the way back to the 216, 235, and 261 stovebolt engines.

Awesome! Thanks, Jerry! greatly appreciated. I may just shell out for the book. Looks like something I should already have on hand anyway. I'll let you know.
Thanks a million! You're the best!!!

The only difference I know of is the early models up through 66 had smaller bolts for the flywheel. 7/16 on the early ones & 1/2 on the later ones. You can use the corresponding flywheel or I used to drill the older flywheel out to 1/2 when replacing an engine.

Thank you very much for the update, Wrenchbender Ret.!
I guess I'm covered either way. As I recall, both flywheels were identical -- save the bolts I guess.

Thanks again!
