Leave the Motor Mounts to Us

We understand that replacing the frame mounts and motor mount adapter plates is the foundation of a successful GM LS engine replacement. Adapter plates bolt onto the engine block and secure it to the cross member. We have adjustable and stock location adapter plates available to create the perfect fit and maximum stability.

Most car applications require the LS engine to be moved forward due to firewall clearance issues with the passenger side cylinder head. For GM LS and LSX engines, we recommend 1" set back adapter plates to retain the factory transmission cross member and driveshaft distance.

LS Engine Swap Cost

General Motors offers a powerful and affordable engine. Making an LS engine swap convenient and affordable is our highest priority.

Our goal at Cousino Performance is to help you estimate the cost of your LS engine swap by considering the driving application and your style. LS3 series engine swaps are popular for street applications, while the LS7 series is for trucks and off-roading applications. The LS3, released in 2008, was the most powerful Corvette engine. The LS7 provides more horsepower for greater towing capacity than the LS3 and is the largest LS engine built by GM Performance.
