Compression question

When looking for percentage differences as in to find bad valves, rings and such, it does not matter. If you're looking for total cylinder pressure, sure, block the throttle open. But for diagnostic purposes, you can do it either way.

After reading all your compression tests I decided to test mine as I have just put a larger cam in my 410 stroker. Hughs roller hydr 234 in 238 ex on a 110 lobe separation. # 1 was 195 # 5 was 193 and #7 was 195. I stopped at this time as I thought these were good numbers for this cam.
