383 Flywheel swap to 440

[193rdsow]

Can a 69 383 HP Flywheel be swapped to a 69 internally balanced 440?

Is the Flywheel neutral balance? Bolt pattern to the crank is the same

All 383's are internal balance, as all were forged crank. At least if I remember right. So. If it bolts, run it. And if its a 69, its internal for sure.

if it is internal to internal it is perfectly find. the only thing to watch out for is the 142 vs 130 tooth bellhousings - make sure you have the correct bellhousing and flywheel arrangement
