iunno all i remember is that it was about .094 down the hole using the 3.0 v6 flat top pistons. stock bore. results using the pat kelly calculator.
I ran Poston V6 hypers years ago with dbl sided valve reliefs. Don't think they were any more than .055 in hole.
I think the mufflers killed the most power. There was a notable butt dyno difference. Theyre just cheapo Flowmaster knockoff Thrush mufflers.
Made more power. Was a point higher this time, 11.8:1. Tbh I could get away with another point. I do genuinely think the mufflers had the most affect.
