Plug depths and compression tests
Just got through rebuild and moding a 225X motor today, shipping it this week, we machined heads to clean up damaged and replace OEM O rings ( looked as good as factory by the way , both water and compression side !!! ) Did compression tests and all with in 1-2 lbs, tally was a litle lower than I expected until I figured out the compression testor plug side adapter is short ( 1/2" thread ) the 225X motor is long reach ( like a Big Block Chevy ) SOOOO IF the compression fitting was to go to the correct depth as the normal long reach plug it would been right on my targets of 140 lbs at sea level..
Just food for thought..
