thanks, i thought that it could be done on engine likes the engine is not tore down, do you have a measurement from a 239 stock piston that you could give me from the center of wrist pin the top edge of piston, by the way the the new 3 3/8 pistons are three ring pistons tell me and tell me if your measurement is to top edge or at the slight dome thanks so much, steve this would help so much
