  • 5 year 100K warranty on our Daily Driver builds with upgrade-able options
  • By buying you agree to have the engine core ready for pickup and return to us within 30 days of receiving the engine.
  • Failure to do so will void your warranty.

Core will be inspected and must meet our specifications to deem it a good usable core. Mainline and crank must meet our specs as well. The engine will be shipped to choate engineering performance in shrink wrap on a non returnable wooden pallet & the appropriate core charge due.

Once inspected appropriate core fees will be kept and balance remaining will be refunded promptly in the form of a check.

We require a like for like core- meaning if we send you a long block we require everything from your core long block to be usable and machinable.

  • We will need the year, make, model, and vin number to make sure you are buying the correct engine before we ship.
  • We must know if the transmission is manual or automatic as this effects prices and usability.
  • If transmission is manual, we suggest purchasing a flywheel so we can balance it to a new flywheel.
  • If customers flywheel is used the engine will be balanced to a stock flywheel.
