Description
TSP's motor mount adapter plates allow you to swap any LSX engine into hundreds of GM applications, including most 60's and 70's Chevrolet or GMC pickups and cars, such as the Camaro, Nova, Chevelle, and Impala. CNC-machined, they're precision-cut to provide a secure fit to the block and motor mount, with four mounting positions designed to accommodate just about any setup — regardless of headers, oil pan, steering pump or box, and similar clearance factors.
