Let's put a mild 8.2:1 360 on the dyno.

I think if most of the non race car drivers on here
would build high torque motors instead of lumpy
don't come on till 3500 rpm motors, they would be
a lot more happy.
400 fp of torque is big block grunt in a usable range.
I hope you come up with a formula that can accomplish this
and can be easily repeatable for the average joe.
