Larry's Shee Posted January 18, 2015 Report Share Posted January 18, 2015 Finnaly found what was wrong with the shee, turns out the cylinders were bored 30 over by the previous owner who told me they were stock, so i had put stock pistons in, now im redoing the top end with the right pistons and a good cylinder honing Sent from my iPhone using Tapatalk Bet you still didn't measure the bores, did you? If they aren't round and straight you're wasting the price of new pistons, and may cost you even more when it blows up. But ring gaps were good... lol Nice and big, like an 8 mile whore. .303 piston clearance and .045 ring gap it's a wonder you had that much compression. Never trust a previos owner much. Always verify it yourself. Receipts, eyeball, micrometer, calipers, compression gage, etc Quote Link to comment Share on other sites More sharing options...
