I put a compression gauge in 5 different cylinders there. 3 on one side and 2 on the other.70 psi was the highest. So I just went out tonight and did a compression test with the carb wide open using 3 different gauges that I checked to my air compressor which shuts off at 120.

Wow, are there rings on those Pistons? Seriously, check the cam again, I was 2 1/2 times that with a 7.90 lift cam and 15.19 cp. Do the leak down first. What type rings.
