I'm looking at the engine mount adapters for an LS1 engine onto SBC frame mounts. The TCI chassis I have was built with frame mounts for a SBC/700R4. I got an LS1/4L60E combo yesterday that I want to use instead of the LT1/700R4. Looking thru the Welder Series catalog, I noticed they offer an adapter plate for the LS1 engine that uses the early style SBC engine mounts that are supposed to fit the SBC frame mounts. In the Jeg's catalog, they list a Trans-Dapt adapter that does the same thing. Has anyone used these mounts or something similar to drop an LS1 into their SBC frame? What would be the Pros/Cons?

Thanks,
Mike
