Mark From Detroit Journeyman Posts: 29 From: Registered: Apr 2001	posted 05-07-2001 06:52 PM I just recieved my engine back from the machine shop today. I started double checking all there work and am coming up with .003-.004 between piston and bore measuring 90 from wrist pin. The pistons are L2379 forged TRW. The box is marked .0015 minimum clearence mearuring 90 from wrist pin. Is this a little sloppy for a street motor? IP: Logged

Good thing I didnt call the machine shop and make an a$$ of myself. Everything else looks great! I Cant wait to get the old Stang fired up. Mark IP: Logged
