Hot Rods Hemi Flywheel question

Is the flywheel the same for a late 354 and the 392? The 354 had 172 tooth starter ring.

 

As far as I know. I used an early Webber flywheel and cut it down to press on a Pontiac ring gear. To fit in the Chevy blow shield. But i am pretty sure that a 1957 354 flywheel will fit a 1957 392 Chrysler.

 

Thanks Rich, do you know if there is any balancing issues? was the 392 balanced different from the 354?

 

I only had an early long bell 331 and a coupe of 392s. But they were all internally balanced. The flywheel was balanced separately to a zero balance and would go on any Chrysler product gen 1 hemi or poly.

 

^^^^ and also the flathead 6, but some were only drilled for 4 crank bolts and most had 8 crank bolts.

 

All pre-62 v-8 and L6 flywheels mounted/registered the same to the crank...well, back into the 30's anyway.
If you look around, you will find 4-bolt, 6-bolt, and 8-bolt versions all on the same bolt pattern so all will swap.
The 146 tooth and the 172 tooth do not interchange directly due to the change in diameter. The flywheel has to match the bell so that the starter will engage. If you are using one of the old-timey cast bells (Cragar, Trans-Dapt et al) then it is most likely set up for the 57-58 starter plate which requires the 172 tooth ring. If you use one of the thinner plates (53-56) then the trans moves forward and must be accounted for.
All pre-69 Mopar engines, are internally balanced.

73RR.........your the bomb !

 

Installing an early Cragar cast bell housing for a chevy transmission. the starter plates I have are 3/4 and came off an 331/354. The starter and 172 flywheel match up perfect. However when you install the Cragar casting the cup over the nose is not in the right location.. and is obstructing the starter from mating up.. before I start modifying the adapter I would like some input..Thanks

 

bump up.....
