Putting together a 347 build and have 2 cams currently. Keep going back and fourth on which one to use.

Details on the build.. 347, 9.3 CR, Dart block, AFR 185 renegade heads, trick flow box R, on 3 kit with 78mm

First cam is just a F303 with 1.7s 226/226 544/544 114 LSA

Also have a custom cam that was specd for a turbo 347 but bigger turbo/heads. Specs on that are 234/228 558/569 115.1 LSA

You guys think that custom would work better in the setup than the F cam? Was hoping for 650 rwhp through a C4 with 15lbs with the F cam. Just know i can get away with a little bit less spring pressure and cheaper lifters with the F cam. Dont mind spending the money on the better valve train to run the custom cam if i get some feedback that the custom cam will in fact work better.

No street time, just a track car. Dont want to go crazy with the RPMS, plan to shift it by 6500

I don't htink either one would hold you back from hitting your HP goal. The turbo and kit might.
