These suit the standard 850/903 conrod and use a 20mm sized press fit gudgeon pin, so a direct fit into 850/127 engines (with offset overbore). 67.2mm bore is 965cc capacity, these at 67.6mm oversize is about 980cc. The price INCLUDES the correct head gasket to suit these big bore pistons, which allows for the factory style offset bore required to use them. High performance, higher compression option for the OHV engines due to the increased swept volume. These are NOS and are no longer in production.

ARP head stud and main stud kits, GMB water pumps, OE Fiat oil pumps, Graf timing and oil pump drive gears, Akron silicone engine seals, Pirelli timing belts, Fitchel and Sachs clutches and much more, just enquire.
