RTS motor mount adapter plates allow you to swap a newer LT 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 are precision-cut to provide a secure fit to the block and motor mount, and they have been designed to allow four positions in order to accommodate just about any set-up, regardless of headers, pan, steering pump/box, etc.
