Thanks for the reply's. IM rebuilding the engine and planning on getting new pistons. Is this the cam your talking about which would be good? This is the cam I have Summit #5200
Specifications:
* Advertised duration: 262 intake/272 exhaust
* Duration at .050 in. cam lift: .204 intake/.214 exhaust
* Gross valve lift: .484 in. intake/.510 in. exhaust
* Lobe separation: 112 degrees
* RPM range: 1,500 to 4,000
Would you go any larger on the cam? With the Keith black Pop up pistons would it be the same as running 4v closed chambered heads? Hopefully the OC 4bbl heads, pop up pistons, cam, headers, intake and 4bbl carb I should make 300HP? or is this a far fetch?
Thanks,
Jim
