Our LS engines feature a Hotrod/muscle car type oil pan.  You will have to specify if ordering for a GTM. The pan will either need changed by us for additional cost, or you will need to swap it yourself.

Sold as a stand alone engine only. BluePrint Engines does not offer GTM transaxles, or transmission control.

This engine requires a non-weighted flexplate/flywheel.

Recommended Fuel: 91 Octane
