Just did a compression test on a 02 ls 3.9. Its got 115K so I figured it was about due. The results were 230-235 psi after 5 cranks in each cynider. I couldn't find any specs on the internet so I didn't know if this was within range. I heard you want them all within 15% of each other. Anyone got any specs. Thanks
