Coast High Performance Crate Motor, Long Block and Short Block Limited Warranty
COAST HIGH PERFORMANCE warrants components against defects in our workmanship and material in accordance with the schedules and limitations outlined below. Repairs or replacement will be made at the COAST HIGH PERFORMANCE factory within a reasonable time after notice and upon receipt of the goods deemed to be defective per the schedules and limitations of our written warranty. A warranty case number must be assigned and repair instructions provided prior to repair or replacement of goods.


  • Long Blocks - 90 Day Limited against parts and workmanship

  • Short Blocks - 90 Day Limited against parts and workmanship
  • Long Block and Short Block Limited Warranty Explanation:
    The reason that our Short Blocks and Long Blocks come with a 90 Day Limited warranty against parts and workmanship is that once a Short Block or Long Block is sent to a customer we no longer have control of whether the motor is professionally dressed out, assembled, installed, tested or tuned. These are all factors that can lead to a motor's demise if not done properly.

    This is not to say that we do not stand behind our products and experience! We have a reputation to preserve and on which we rely to continue to provide Short Blocks, Long Blocks, Crate Motors and and countless other performance components (basically we depend on a good reputation to keep us in business). This reputation is what has kept us in business for over 20 years.

    If in the event something goes wrong with one of our Short Blocks, Long Blocks or Crate Motors after it has been installed and run, we work with our customers 100% to find the cause of the malfunction and get them back up and going as soon as possible.

    Coast High Performance does not approve and/or authorize any other shop or persons beside Coast High Performance to inspect the engine. Nor will we reimburse any outside labor or parts charges.

    Fuel injectors, fuel pumps, water pumps, hydraulic high pressure pumps, sensors, sending units, turbochargers, belts, hoses and other accessories installed have a one year warranty, after which time they are considered maintenance items and are not covered by parts or labor. Parts included in installation kits are covered for the time stated by the manufacturer. Does not include problems related to fuel components and accessories not installed by COAST HIGH PERFORMANCE.
