Those old TRW Forged psitons were designed with a lot more room at the top to allow for heat expansion. What is the clearance in the wrist pin area, about 1 inch below the oil ring? I think you will find it is a lot tighter there and that is where they were measured for machining clearances. Old Geezer Racing

HodRod, yeah I cc'ed them yesterday, and they came in at 62cc's which surprized me. I have another set of J heads with a 2.02 stainless valve and it cc'ed at 68-69cc's. I quess they were milled a decent amount, plus I'm sure the manley valves add to it not nearly as dished as stockers. 6233006-2010-10-03004(Medium).JPG (86 downloads) 1972 Duster 318 4 speed 1958 392 Hemi engine waiting to be built!!!!!
