I'll nose around some specs just for some fun and see what's out there. I assume you'll use a KB hyper piston that's readily available and your head cc will be in the 70/72 range with the "J"s and 66/68 range with "X"s. In the end a dynamic comp. ratio in the 8.0/8.25 range will allow you to not worry about premium pump gas quality. Also, with the manifolds, a split duration cam will be a must to help get the exhaust out.....Just my opinions, so others don't chop my head off........lol. Later, Rick
