I need some opinions.
OBX's specs on their cams are:
Stage 1: Duration (Lift mm): IN. 256, 9.0; EX. 256, 9.0
Stage 2: Duration (Lift mm): IN. 264, 9.0; EX. 264, 9.0
Integral's specs on theirs are:
Stage 1 248° .343" (8.71 mm)
Stage 2 254° .360" (9.14 mm)
Stage 3 260° .375" (9.52 mm)
Does anyone have an opinion of which is the best application without changing the valvetrain?
I THINK that the OBX would be a better bet, having not as high a lift, but I'm not sure what the duration is going to affect? Them stage 2's have a longer duration than Integral's stage 3's.
Opinions welcome, desired, wanted!
