I'm thinking of building my 383 HP to a Blueprint/Purestock spec. It will go in either a 70-Bee or RR 4spd.

I'm curious about how to get the 9.5 cr. with the limited pistons and CC's.

I think I have the 2315 pistons and the depth is at .105 in the whole. I can't see a 79.5cc head helping much (apx. 8.3).

How do I accomplish this? Do I deck the block .070-.080 to make it work?
