I believe it is .0008” with .927” DLC pin. Clearances were set at GibTech. Bore is 4.240”. These are billet inboard wrist pin guided pistons with .007” piston to cylinder wall clearance and a filled cast iron block. Oliver 5.850” I-beam rods.
I notice on my 1st post I sad 7,000 RPM. That should have been 8,000 RPM max. Most likely will be 7,600 - 7,800 finish line RPM.
