compression ratio to cylinder psi

My guess is that with "only" 157 PSI, no extra machine work was done such as block decking or head milling. IMO, it probably has 8.8-9.1 static compression. I also think that if that cylinder pressure is correct, a smaller camshaft would provide a power increase by increasing cylinder pressure. That said, it's probably a pretty nice little combo for a street motor. How does it run?
