Flywheel integrity

What? should that be "shock", maybe?

My 451's low-end torque is quite weak with a 272 cam, so the extra mass helps there. Wouldn't a lighter flywheel require higher rpm at launch?

LOL...my fingers aren’t working too good today. I fixed it.

With 451 inches I can’t imagine you need more flywheel weight. Unless you have a 3.23 gear or something and the car is heavy...like 3800 pounds or more.
