General Motors vehicles are known for their versatility when it comes to swapping parts from chassis to chassis. The introduction of the LSX engine abruptly halted the ease of interchangeability between muscle cars and modern cars. Today the LSX engine swap is a very popular swap in the Pro-Touring community, but until recently it required serious fabrication to complete. ATS tackled this obstacle by machining up a set of aluminum engine adapters to locate the older style three-bolt engine mounts, to the modern four-bolt engine block. By flipping the engine mounts upside down, the LSX sits lower in the chassis, and as far back against the firewall as possible to promote good weight distribution and improve center of gravity. The plates allow a direct bolt in of an LSX engine into the engine bay of most GM muscle cars and include all needed hardware. Optional polyurethane Energy Suspension engine mounts available for $60 per pair but are not included at the $140 pricing.
Note: Factory oil pans and A/C locations will not fit into chassis without modification or replacement
