Just did a compression test on the '96 Expo.5.0 and I'm not sure what the results should be.
Engine was stone cold and outside of the TM headers, box stock.
Throttle body wedged wide open and all 8 cylinders were between 130 and 135 psi.
I'm pleased the results were so even but are those results within reason?
Basic math has about 140 psi the max the cold 9.5CR 302 should produce but my (probably fading) memory had me expecting more like 150 to 180 psi.
Yea, I know a compression test should be done hot but I'm simply to much of a wimp to try the test on a hot engine in such a tight engine bay. I'll leave the deliberate branding to the masochists.
