How your engine is built.....

First, the block is cleaned in soap and water, then entire casting is de-burred, and checked, and sent out for re-sleeving. When your block is returned from sleeving, it has been hot tanked, surfaced and bored/honed to size. We then wash your block with soap and water (again), and blow dry it with air. Your crank is crack checked, micropolished and balanced. We choose DPR Pistons and "Total-Seal" rings for all our builds, as we consider them to be the finest piston made at any price. DPR rods are chosen based on your request. New Coated bearings are used. New/DPR Modified OEM oil and water pump will be installed.
