Below you will find information about your core engine, shipping and our warranty. If you have any questions, please feel free to email us at


Each engine has a refundable core charge 

Not all engines are going to bring a full refund. When it comes to your core, remember 2 things. 

1) We would much rather have your good core engine then your core deposit (we can’t build good engines without good cores).   2) We are very choosy about the parts we use in our/your new engines, so we have to be the same way about our blocks, rods and crankshafts. We build excellent engines (that’s why you're here, right?) Even if you have a bad block or crank there is almost always something that is good. Even if some of your core is bad, we will give you some of your core return on the components that are good.

Core Engines can NOT be picked up at the time of delivery unless you have it strapped down to a pallet with the oil drained ready to go. And you HAVE already made arrangements with us to have it picked up at the same time.

It works out best if you reuse our shipping pallets when returning your core engine. Please call us with detailed information on the day and hours of operation to schedule the core pick up. You may also bring your core to a freight carrier for a cheaper rate. Please call us to make these arrangements. Also, please remember that the shipping cost of your core engine will be subtracted from your core charge that was paid with your engine purchase.
