The machine shop told me I would be alright with a .020 over bore so I ordered the 9:1 wisecos, got the block back from the shop and 3/4 pistons and rods installed. The fourth piston had a mismanufactured ring which snapped in half. Wiseco sent me out a new set of rings and I'll get them in in the next couple of days. I went with a 0.017 gap on the top ring and 0.019 on the second ring. Does that sounds right? And I have the crank girdle in with the factory bolts, but I'm starting to wonder if I should go with arp's before I put the oil pan back on.
