OK, am I missing something, or are Buick 350 flywheels RARE ? I've done some reading and it appears that the 225 flywheel can be re-balanced to work with the 350. (I'd rather not go this route) Is there a good source for Buick 350 flywheels that I am missing ? (Obviously the cheaper the better, but without compromising safety/durability) If I could find a Buick 350 flywheel, I'm really considering the swap. ANY help would be appreciated !
