I'll be watching this, as I have another 372 stock, also 2 more oem p&c's to work with, and windowed & unwindowed pistons.Yes to all. Very cheap bolt on power. $35 piston, few bucks for machine work. Trappermike seems to think a windowed piston works better in the 372. I can’t say that’s true or not. 268 piston with minor port work will blow the socks off a xpw all day any day.
In a few weeks I’m going to compare the 268 windowed piston to the 268 non windowed piston.
