NOTES:

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.*

WARNING : This product can expose you to chemicals including arsenic, which is known to the State of California to cause cancer. For more information, go to www.P65Warnings.ca.gov
