I'm wondering about h.p. difference between Solid Roller & a Flat Tap. Same specs on both. All Roller valvetrain being used. I'm just interested if you took your motor and set it up on a dyno, and just swapped out cams, how much peak H.P. diff. there is.

If both cams have the best lobe designs the roller lobes will make more power and raise the peak HP and torque RPM up by several hundred. How much actual gain Maybe twenty, maybe more
