Quote: Maybe this will give you a few ideas. We invited the neighbors over for a 'dyno day' at the shop and made a few changes to a 7.5:1 compression 440 over about eight hours and made a dyno pull after each change. It wasn't designed to be a perfect combination, we started with stock 906 heads and used parts we had laying around.
Low compression 440 dyno test.
400 seems pretty easy as I suspected. I would think it might have done even better with the 528 solid.
