.555/.576 lift with 1.6 rockers
110 lobe sep
I might have to drop the compression a hair to use this without pinging. Tell me what you think about the cams. Suggest something else? I want to hear. Should I advance the cam a little? Remember this is an all street car that weighs 4000lbs. I would like a decent sounding cam but im more concerned with function. I've thought about going with a 106 lobe sep but i think id have to lower compression more. Im open to ideas.
