Just another cam pick question.

I found this cam that looks to keep a higher cylinder pressure for a low compression 1972-up LA 340. Any comments, please?
I have the 108* 484 lift Purple from 1978 and it's got 125 lbs/ each, too low and I think it's due to the 108* separation. I does run 12.80 et @108mph.

The 108 separation is a moot point, it's where the cam is installed. That same cam on a 114 separation has even less compression. The 114 has less overlap and will have lower cranking compression, ummm wait, that's opposite from everything you've ever been told... Cranking compression is based on when the intake valve closes, not overlap.

If you have adequate valve to piston clearance, install that 108 LSA 484 cam at 100 in a low compression 340 and watch what it does... :) BTDT.
