Yep, 114 for a strong vacuum signal and good mid to upper rpm pull. You have a loose converter, so bottom end power will not be a problem. The intake closing point on this cam will put you right at 8.0:1 DCR and should work real well with pump gas if you have a tight squish in the motor. If you want a little more bottom end and rump-rump in the motor, you could specify a cam with a shorter lobe center, but try to keep the intake closing point at about the same place as the cam I showed you.
1JohnnyO, he could very well use more cam in this motor, but efficiency and power will be down because of a mismatch. When I suggest a cam to someone, it is matched to the static compression ratio of their motor in order to provide maximum compatibility and power for the c.r. they are using. If you want more cam, then build more static c.r. into the motor when you are building it. THE STATIC C.R. AND THE INTAKE CLOSING POINT ON THE CAM MUST MATCH UP or you will end up with a weenie that either will not make power or one that detonates on pump gas.PLANET EARTH, INSANE ASYLUM FOR THE UNIVERSE.
