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..

Cheers Jay

Forged wizards pistons

Hey Jay,

just a quick thanl you for some amazing work ,those forged wizards pistons and balanced rods are a serious bit of class,nearly too good to put into the engine.
All i need now is to find my detonation issue to run them as they should be run.

thanks Jay.

Your VERY welcome, great doing business with you....Timing cannot be any higher than 25 degress at sea level and WOT..Also add some more fuel amount, also you can add some more quality or higher octane as higher octane fuel burns cooler and less likely to detonate..
