Really ? Multiple people have done testing with the pre eagle intake manifold/engines and have gotten 600+ hp out of them so how bad is the intake actually? I call bull**** , it might no flow quite as well as the eagle and the rpm range is slightly different but it’s not a terrible intake.. I myself have +\- 550 crank horsepower 2008 5.7 hemi in my charger and it uses hhp stage 3 .030 milled pre eagle ported/polished heads ,stock intake and hhp stage 3 cam … could I get more power with eagle heads & intake? Yes I’m sure I would but is it worth the money? Also why the piston swap ? Did you do it to lower the compression as a thicker head gasket would accomplish that … I’m interested in what your trying to accomplish… not bashing anyone just curious
