LSx Engine Adapter Plates
Let's face it, right now the hot ticket for a top performing and smooth running power plant in your muscle car is an LS engine swap. With modern engineering and technology, previously unheard of horsepower and fuel economy is now available. Having big block power in a lighter and smaller package can also enhance your muscle car's overall handling and performance.
ATS was amongst the original instigators of the LSx swap movement, and one of the first to produce a simple and effective way to install one of these engines in an older muscle car. Made in the USA from 6061-T6 billet aluminum, ATS LSx Motor Adapter Plates are CNC machined for a precise fit. After final machining they are black powder coated for a long trouble free finish. They are simple to install and an easy step to get your early model car up to late model speed. Sold in pairs with all necessary hardware.

Application: Universal, fits most V8 GM muscle cars. Some later model cars may have to convert to early style motor mounts (Speedtech part # 220530) and factory frame stands.
