Disappointing dyno results

You have to cc the cylinder with piston at TDC and add that to the combustion chamber area to get accurate CR.

When you have your cam set at 106 ICL, intake open point is measured at.006 for a mopar cam. Forget about what it is at.05. That is a measure of how fast the valve ramps up on the cam.

Jet your carb main jet so you have A/F slightly lean at cruising rpm. It should be slightly rich at WOT to make the most horsepower. I don’t know how to do that with a carter avs. You are too rich through out your power curve. Did the dyno operator change main jets and the metering rods?

What brand cam are you running and exactly how much horsepower are you looking to make?

Hi ch1ll. Regarding Carter AVS. Dyno operator only had a lager Holley which yielded similar results. He will receive 600cfm Holley for pull tomorrow if weather permits. Humidity is currently high. Operator does not have any replacement jets or metering rods. The Carter I had rebuilt was stock unit for 68 or 70 340 4 speed application. Can't remember which. Would only think jetting would be correct.

Cam is from Camcraft. I know, you never heard of them. Wish I hadn't. Only looking to make stock horsepower. That's all I can expect using stock engine components.
