Hi Jim, Randy at dyno might be a good source for this min number. I know I’ve cut some down a lot but I can’t remember the min thickness. I’ll dig around my shop and see if I have any old cut pistons. Most of my engine stuff went with the business when I sold it a few years ago.What's the most you have taken off the top of a Wiseco 2.7325" piston?
Better yet what is the minimum thickness you have used, measured from the top of the piston to the underside, between the wrist pin centers?
And how long has it lived?
