pulled the piston off the wall was hanging on a BME rod
top and second groove are the same size ran a piece of old ring around both grooves no tight spots appears to be your part number there is some unexplained handeling gouges on the botton of one skirt just knock down high spots should work fine also have a good original pin can go with i never figured on using it again, its yours for shipping if you want it

Sooo....I'm supposed to be opening up a 400 that is in a 1970 GTO YS. Very well cared for, compression is still strong on all 8, the engine has never been in to. If we decide to do a full rebuild there would be 8 GM pistons available, unless they can be ringed I guess. Would be in a couple of weeks if this goes as planned...
