I am selling a Cloned R3 engine short block. It started off as a sonic tested block that was good to 0.0120" overbore! I have 7 blocks and this is the best one. I had a set of NOS R4 pistons (with spiral lock grooves from the factory...yes this was an option, but most were press fitted) and milled the dome off. This converted the piston from R4 to R3 as the only difference is the dome. What I am selling is a block with 0.093" over ForgedTrue pistons, a paxton SN 60 supercharger, and assembled with factory connecting rods without the "pinch bolt." The rods have been polished and shot peened. The engine has no oil pump, cam, timing cover, timing gear etc. It is only a block, crank, rods, Paxton Supercharger, NOS pistons, NOS rings, and rod bearings all assembled. And as always, everything is show/museum quality. Let me know if anyone is interested here or I'll just post it on Ebay.
