Hope this will help

Comp Cam.part #12-432-8
Adv Dur: Intake,282 exh.288
Dur@.050 Intake,230 Exh.236
Lobe Sep: 110.0
Valve lift; Intake,.510 Exh..520
that cam isn't for building off line torque as the close lobe sep will bleed off cyl pressure at lower idle. That cam will not make good power below 3000rpms. Sometimes less is more.
