Which flywheel for bbc
Does anyone know the gm part number for
A flywheel for a 454 1 pc rear main, 168 tooth, for
Internal balance crank.
Seems to be a lot of confusion on this subject.
Thanks to all

Don't think one was ever made for a one piece seal 454. They do have internal balanced type flywheel on a 572 crate engine. The thing in question would be if your coupler would bolt to it beings they use a 11 1/2" clutch compare to 11". #12582964 is the part number.

There are aluminum ones, not GM which are drilled to work with several different size clutches. Not cheap and don't if you would want an aluminum one anyway.

A stock 454 wouldn't be internal balance, not saying it couldn't have been internally balanced at a machine shop. If it truly is internal balance then the 168 tooth flywheel off of a 427 should work.

After fooling with 454's for decades I would never swap flywheels with any other motor with out taking it and the balancer to a shop to be balanced.
How come your motor is internally balanced?

More info
I have a 454 1pc seal block. mark v
I need to buy another crankshaft and decided to go with a 4.25 stroke because I already have correct rods/pistons.
I also need flywheel and HB.
I noticed that internal bal stroker cranks are much more abundant.
I figured it would be easiest to go all neutral.
Guess I was wrong?????

I just had the same deal when I stroked my GEN VI to a 489, I took my OEM factory flywheel, ground out most of the counter weights and then took it to the machine shop and for $40.00 had it nueral balanced. Done Deal. Just my 2 cents
Make sure you get a new harmonic balancer to match. Don't use your old one, it was for an externally balanced set up
