I was running a compression test on my engine last night and couldn't find the spec in the Specifications page. Anybody know what the spec is? Half were 140, the other half were 150.

that good as long as it fairly even and I assume that you were testing it cold, so that would be right on a stock engine.1991 Grand Prix STE
