It's around 36 degrees . I put light springs (really light) and recurved the distributor . Something like 16 initial 36 total all in by 2200 rpm.
Had MP 590 solid in motor ( way big for my combo...but all I had at the time ) car would run 110 in the quarter no matter what gear 3.54 or 4.88 or timing setting from 32 degrees to 38 degrees . Best time was 12.5 @110 with a 1.6 or 1.65 sixty foot (can't remember).
After swapping cams gauge pressure went from 160 psi with .590 cam to 185 psi with .528 cam . Way more bottom end performance with smaller cam with no perceivable loss of top end power .It's a much better match for the rest of the combo.
I haven't taken it to the track yet to see what it runs with the small cam but the car is violent off the line.....Hopefully it'll break into the elevens !!!
