Disappointing dyno results

Saw your post on compression. What did I miss in my calc?

Your right. I am very frustrated. So much so I would rather start over on a different engine.

I think my dyno guy is OK but like said earlier, he should have installed cam. That is my fault for at the time did not know one hade to degree a cam. Not that it's very difficult but was involved. Likewise to cc combustion chamber. I enjoy learning new things.

I do want to run my AVS. Based on numbers, I see why he want to run smaller carb but think he is going do the wrong path.

A few degrees of cam timing will not give you that much deviation from a stock 340... There is either something totally broken or you need to try a different place to dyno it.
