compression ratio

does anyone have a chart or know of a sight that has a chart/conversion equation that converts psi to compression ratios?? i did a compression check on my motor(good ol' 350) and it was 155psi on most cylinders. the most difference was a 10 psi difference. although the motor was cold when i did it though.

Re: compression ratio

Theres no formula that converts psi to cr. The relationship between the two is dynamic and complicated.

Why do you need to know the cr?

155 psi sounds fine for a stock 350.
