I just bought a 383 stroker from a buddy. (He had built at a speed shop) I installed it into my monza last weeK. After breaking in the engine. White smoke started to pore out the passenger side tail pipe. we checked the park plugs, and one of them was wet. we put a new one in. and after 10 min it started smokeing agian. We did a commpression test. came up with 170.We where getting spark, so the distributor was fine. so we pulled the head, everything was good. but the cylinder was shinny clean. pulled the engine and piston, and noticed that the 2nd commpession ring was a little sticky. put new rings in the piston and ran it agian, still smoked and plug was wet. Any ideas???
