OK...What is the most lift that can be used on a 400 with 9.4:1 flat top pistons? I know how far down in the hole the piston is would also come into play. Lets say the block was 0 decks and has 915 heads on it. Everything else is stock.The motor still has the heads on it so I am not sure where the pistons are. I bought the motor rebuilt.

Thanks
Rick
