My head cc are 65 intake runner 179 exhaust 67
.40 bore and 3.58 stroke. Gasket size is .49
When I used a compression Calculator brought me to about 10.75 to 1. Just wondering a rough horsepower estimate
If not, get the casting numbers off the head and there's a typical measured CC for stock heads. It's a guess because you don' know how much your head have been surface cut or milled. But it will put you in the ballpark.
IMHO, that cam, strip dominator single plane, and 670 cfm vacuum secondary carb seem like a slight mismatch. I'm thinking more carb or less (dual plane) intake.
