I would personally try to go with a flat top piston and a closed chamber head.The Blue Thunder intake is a dual plane design as far as I know.I ran one for a while and it was amazing!I would recommend a cam in the .550" to .575" lift range and a duration in the 240-250 deg @.050 range on a 110 centerline.This is very simillar to the Cleveland I had in my Pantera and it made 340HP at the wheels.If you want the absolute best advice give Mark McKeown a call @301-246-9225.He is very helpful and an absolute genious when it comes to Clevelands.
