One thing we pride ourselves on is race proven performance and reliability. Never settle for something that just “works”. All of our products were designed to meet our specifications and expectations. We feel that if it isn’t good enough for our track cars, it isn’t good enough for your daily drivers or personal track cars.

Every motor goes through a rigorous evaluation process to ensure the quality and reliability of your new built motor is second to none. Before assembly each motor (whether your own or a core we supply) is torn down and inspected, washed, and measured to ensure everything meets our specifications.

  • Disassemble motor and deep clean of all parts
  • Inspection and measurement of all parts to be reused.
  • Install main girdle and torque plate
  • Measure main and rod bearing journals
  • Clean before final assembly
  • Install rod bearings and measure clearance
  • File fit rings for individual cylinders as needed
  • Install crankshaft with new front and rear main seals
  • Install pistons, rings, and bearings on the rods
  • Install each assembly into the block
  • Check crankshaft for breakaway and rotating torque
  • Final cleaning and inspection

A core charge of $1200 applies to the N55 engine, shipping is generally $300-$500 depending on shipping location and whether a forklift/loading dock is present.
