Well tearing down for DOD issues and did a compression test just to see where its at. #1 is at 215 psi, the rest are at about 220. I thought that was pretty good (have build gen 1 engines) for the mileage. But now see on here most people seem to get about 260 to 270 or so. Searched the internet and didnt find much, maybe looking in the wrong place. 90k on the motor, but ran great before the lifter issue. So am i looking at a bottom end in your guys opinion?
If so going to put 6.6 rotating assembly in it for a few more cubes. Might as well.
