Thanks rumble. It not the best cam for my combo but I have it. Current motor is actually 9.8 to 1 with home ported j heads 2.02 1.6s. I was going to shave the heads .040 to get to about 10.25 with .028 gaskets. Changing my combo a lot. 4500 stall 4.10 to 4.30 gears 26 in. drag radials, tunnel ram and 2 340 avs carbs which are on it now and I love this set up. Old set up 3.55s and 2400 stall. Hoping for 11s
