I went with Total Seal gapless top ring/Napier second ring and low tension oil ring. Pistons were sent off to have the skirts coated with some proprietary coating that added about .0015 to the piston diameter. This was done to compensate for the .002 over the cylinders were honed to remove the grooves from the debris. I used the total seal quick seat in the cylinders and coated everything with their TS1 to seat the rings quickly. Rod bearings were all set to .0028 to .0032 per the GRP spec of .0025 to .0035
Also went with a new Charlies pan that was built to my drawing for use with the swinging pickup. It holds almost 9 quarts under the crank throw without changing my ground clearance. I did a small kick out that is slightly raised off the floor to add volume, but keep all of the available oil in the sump area. This has Charlies newest tray design (full length without a pump).
