Introduced in 2004, the Series III Supercharged engine has 20 more hp than the previous generation 3800, which is due to the improved Gen V Eaton M90 Supercharger compared to the series II's Gen III Supercharger. The engine also features stronger connecting rods than its older counterpart.

A Core engine is a rebuildable complete engine which currently is essentially a bad engine.    The only guarantees of it's condition that we make is that it did not fail from a spun rod bearing, and the block will not be "windowed" from parts going through it.  Other than that, it can have a number of different possible issues, including but not limited to things like high miles, blown headgasket, bent valves, broken pistons, etc.  It will carry no warrantee.

All other engines will carry a 90-day limited warrantee from the date of purchase.  This warranty does not guarantee against leaking gaskets as this is a normal occurrence with engines over time.  We can offer options to replace any necessary gaskets at an additional cost on a case by case basis,

*Engines do not come with any accessories

Because engines are purchased to meet customer's mileage requirements, once ordered, they are considered a custom order and are therefor not refundable. Details of our return policy as well as all our other policies are posted on the Policies page of the website
