What cam are you going with to get 375rwhp through an AODE? Thats going to be really hard to reach. My good friend has a 331 with Stage 2 ported Trick Flow heads and intake, along with a FTI custom ground cam. He put out 340rwhp through a TKO and he had a proffessional tune. Also just to clarify, the owners of Fox Lake told me that most GT-40X heads they see flow less than 200cfm on the intake side. More like 195cfm.
