1.Thanks SS....this means internally balanced crank right?
2.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?
3.Are these flywheels (153 tooth), all the same diameter?
4.I believe the flexplate I removed was about 12 3/4" in diameter....so the new flywheel should be the same?
1. Just by looking at the crank flange, as long as its not a 400 crank, YES.
2. YES. The 400 crank would have a weight on the flywheel, as well as any one piece RMS crank.
3. As far as I know yes. You can use the same starter in the same bolt holes on the block.
