Talked to my builder today and asked about the condition of the internals. He said after almost 30k and around 200 passes down the 1320 that the engine was in excellent condition. The piston skirting coating was only wore off on one piston and that pistons clearance was 5 thousanths. All of the bearings looked brand new.The crank and stock pistons were also in great shape. He was quite impressed with the motor design except of course for the powdered metal rods.

The oil was changed with stock oil at 500 miles after a couple trips to the strip and changed to ow30 mobile one at 1k and every 3k after, just in case anyone is interested.

 

great news!! hope mine has the same luck!!

 

Almost forgot,the manley rods and pistons weigh 38 grams less than the stock ones
