d15b2 Posted July 11, 2009 Share Posted July 11, 2009 I'm currently in the process of building a D15B2. Right now it has pm3 pistons, .010in block deck, .040 head mill, and .027in z6 headgasket. I've tested it with a stock D15B2 cam and there aren't any piston/valve clearance problems, but I am wanting to upgrade to a Delta .400in lift 260 duration cam. Does anyone have any experience with the D15 + pm3 piston combo? Link to comment Share on other sites More sharing options...
