Smokestack Posted October 30, 2011 Report Share Posted October 30, 2011 Hey guys. I got some cylinders and pistons that are fairly fresh and ready to go. Issue is. Compared to my old pistons these are alot longer. And the ports are even different because of the length. Could they be for like a stroker or something? I have stock crank welded and trued.

mopar1rules Posted October 30, 2011 Report Share Posted October 30, 2011 Looks like a long rod piston, versus a stock rod length piston. Quote Link to comment Share on other sites More sharing options...
Zwiser Posted October 30, 2011 Report Share Posted October 30, 2011 what are the #s on the top of both Quote Link to comment Share on other sites More sharing options...
BigRed350x Posted October 30, 2011 Report Share Posted October 30, 2011 I wouldn't use either one. Just buy a new top end kit if you need new pistons. Quote Link to comment Share on other sites More sharing options...
camatv Posted October 30, 2011 Report Share Posted October 30, 2011 one on left is OEM looks like. not sure on the right maybe long rod/ stroker piston. put the pin halfway out of one and push it in the hole of the other. the piston top will be about 5mm shorter on stroker/ 4 mill pistons.. also most have id numbers on top.

Smokestack Posted October 30, 2011 Author Report Share Posted October 30, 2011 Well. Number wise what i took out says o0065 but hard to tell. Long piston just says 1.00. Connecting rod on the crank says 29L. Would that mean long rod? The previous owner said it was a stock crank trued and welded. So who knows.

n2otoofast4u Posted October 31, 2011 Report Share Posted October 31, 2011 29L is a 110 rod a 30L is a 115 rod Quote Link to comment Share on other sites More sharing options...
Smokestack Posted October 31, 2011 Author Report Share Posted October 31, 2011 Hmm. So i have a stock crank. Wonder why it had the shorter pistons in there with stock? I guess i will mount the jugs and stuff and see how the travel is. Quote Link to comment Share on other sites More sharing options...
Smokestack Posted October 31, 2011 Author Report Share Posted October 31, 2011 Well top end is halfway there. The longer pistons fit perfect. No wonder i have had so many issues. Since they even used the wrong pistons before. Sheesh Quote Link to comment Share on other sites More sharing options...
Jereme6655 Posted November 1, 2011 Report Share Posted November 1, 2011 The piston on the left looks identical to my OEM pistons that I pulled out of my bike. Which are cast namura pistons... Quote Link to comment Share on other sites More sharing options...
