[QUOTE="Ironhand, post: 12100937, member: 32955"] Intake Opens After TDC: 4 Intake Closes ABDC: 36 Exhaust Opens BBDC: 44 Exhaust Closes ATDC: -12 Overlap: -16 Lobe Separation Angle (cam degrees): 114 Be very careful how you do degree the cams. Depending on the cams, a piston with valve notches can NOT run as tight as 104-106 ICL. Since these cams are less in duration then you should be fine but you need to check your PTV Clarence regardless. You are aiming for .090-.110 on the intake side and about .100 on the exhaust side for a stick car. You can run tighter PTV clearances but that range is a good safe range. [/QUOTE]
