It is ONE of the many reasons the G3 Hemi and LS work so well. The LS heads are 15 deg really well developed ports and the G3 ports are straight up! Couple that with VVT, EFI, MDS, active intakes and well you just have a fantastic engine. It is also why you stick a cam and long tubes on them and pick up 60-80HP. I intentionally pulled way back on the cam in order to ensure a personality that would suit most end users. They want to go racing? Cam and single plane up and watch the power climb the RPM scale in lock step. J.Rob
