-Deburring of entire engine block removing sharp edges as well as possible stress risers
-Inspection of connecting rods to include measuring large and small ends and ensuring consistent rod bolt stretch.
-Inspection of pistons to include weight matching (.5-gram race balance) and ensuring consistent wrist pin bore size by measuring bores and honing when necessary
-Inspection and measuring of wrist pins.
-Inspection/machining of crankshaft to include polishing of journals and chamfering of oil holes for improved oiling to bearings
