Remanufactured Engines: Better Blocks for Performance Engines 

The foundation is superior to rebuilt engines

Rebuilt Engines - Better Blocks for performance enginesThe quality and reliability of every replacement engine we ship begins with the process used to recondition the engine block. Our methods are precise and proven to far surpass rebuilt engines. First, we thoroughly clean the engine block and check for any defects.  The cylinders are bored to within .004 of the finished size. Next, we use a diamond hone to ensure bore geometry is held within 200 millionths of an inch. Every engine block is then subjected to a surface finish test to measure the roughness and plateau finish of the cylinder wall ensuring proper mating to the cylinder heads.  This is critical to achieve proper ring seal with the lightweight motor oils and low-tension oil rings used in today's car engines.

Blocks are checked and align honed through the main bearing bores to align and size to the proper factory specifications. This is critical to maintain uniform oil clearances and good oil pressure required for standard and performance engines alike.  The same detailed craftsmanship is used for all our remanufactured engines.

After all machine work is done, the block is cleaned and completely grit free. We scrub each cylinder with soap and water and clean all oil galleys with a high-pressure wash.  The block is ready for the next step in becoming the highest quality replacement engine possible.
