It's crazy how all those cams mirror each other till 5500 rpm's. And they say you loose low end torque with big cams.

Wow, thats a great graph. I'm suprised the 224 stayed so close with the 227 and 230. Thats makes me feel better. What other mods does that car have besides the cam?

These profiles are pretty similar. All 3 cams had 224* of exhaust duration and the 230 cam had an ICL 1 degree less than the other cams.
