Cam upgrade for ZZ383.... need input
It's been 3 years now since installing a GMPP ZZ383 in my '69. I'm thinking about changing the cam to get rougher idle. The stock cam pulls a very steady 18 inches of vac, at idle. I'm looking for suggestions for a cam that would not lose me low end torque but get the idle I'm looking for.
I topped off this crate motor with the following parts:
Edelbrock Air-Gap vortec intake
MSD 8360 Distributor
Holley 650cfm vac, sec. carb #80783-1 (also have similar 750)
M22W 2.54 first gear
ProComp 1.6 roller tip rockers(still have 1.5 GM rollers)
Known to run with scissors....
