Thread: Need Help Finding Forged Pistons

Ross racing has the specs for our pistons, bored .30 over.

Might want to talk to them. I have 13 forged Ross Racing pistons here I'll PM you some pics and specs if I can find the damn extra piston ...

PS. The rings SUCKED ! One of the motors drank oil, and dropped a vavle (crappy Comp cams spring) and the other spun a bearing and popped a ring AND bent a vavle.... The pistons themselves are very strong, the one that had a vavle dropped on it survived and shot the vavle through the TOG's .... The motor was actually still running okay with the dimpled piston ....

oh well, that's what you get for 6,700 shifts and a 7,000 redline .....

Others have also used JE Pistons and Wiseco Pistons but like Farns said, they are custom made pistons and no R&D so you may be buying paper weights for $500+! I wasnt really crazy about Diamond pistons for a long time either but learned a lot of thigns about them since. I wouldnt buy them coated as Diamond isnt who is putting the coatings on them and I feel that because of this clearances arent properly set and the side skirts wear excessively. Every set of used Diamond pistons I have seen have worn side skirts and all of the ones I saw WERE the coated pistons, while lots of guys have thousands and thousands of miles on uncoated parts. I also feel that people / machine shops arent properly checking or finish honing the cylinders for the right clearances and this is a larger contributor to the problem. Those pistons will take a lot of beating for sure and I cant say I have seen one with a chipped ring land. Scotty I am in the same boat as you are but decided to face reality.... I dont care if there are cars out there making 600+ HP, HOW LONG do they last in real world conditions with thousands of miles of daily driving? Big deal if a car runs 10s or 9s, thats a weekend pass but means nothing to me as that says nothing about longevity under those conditions. Anything at all could go wrong with the fuel system and stock pistons dont like lean at all or they chip. Diamond pistons uncoated from Intense are $699 and include Total Seal rings. My local machine shop deals direct with Diamond and they can be bought a little cheaper but there isnt much markup on them. You can also get near whatever bore you want whether it be stock, .010, or .020 which is really all you need.
