So. Swapping in a 408 magnum based small block. Everywhere you read motor mounts will work. Just have to shim the drivers side. That is bunk. The teener block has 4 mounting holes. Only three are used tho. On passenger side on this block only has three mounting holes. You guessed it. 318 uses the rear hole. This only has the front hole. Had to cut modify right motor mount.
