Thanks SS....this means internally balanced crank right?
So correct flywheel should be for 2-piece main seal engine, not have counter weights on it, and have the larger 3 1/2" mounting bolt circle?
Are these flywheels (153 tooth), all the same diameter?
I believe the flexplate I removed was about 12 3/4" in diameter....so the new flywheel should be the same?
