Clearancing Piston #8 for crank sproket.
Clearancing Piston #8 for crank sproket. My builder just ran into an issue with my LS2 413 build where he needed to grind down a small section on the base of piston 8 in order to clear the gears that are used for crank timing. I noticed all of the pistons had small reliefs already in them. They were all identical in size, but the #8 had to be enlarged. Did anyone else encounter this? It looked like there was still enough meat on there, but he said that if a piston goes out its going to be that one

. thanks After reading the responces I think I might have poorly explained the part of the piston that needed clearancing. The pistons were custom made for a 4.1'' stroke and custom reliefs. They have very short skirts specifically for strokers. The part that made contact with the crankshaft timing gears, sproket thing was the underside of the piston right where the pin holds the connecting rod. The part that was clearanced came close to the locks.
It will be fine if your guy clearanced the piston similar to what I did on this piston to get the wheel to clear. I've seen engines where the trigger wheel clearanced itself because no one bothered to check the piston to wheel clearance.

great Thanks Steve, that looks very similar to what my builder had to do to my piston to get it to clear. I figured it would be ok, but its good to have someone with hands on experience back me up.
