Well having now found out that the gearbox I got in the sale is for a 6 pot not the 383 I’ve managed to purchase a complete engine and box from a Cadillac for a lot less than the gearbox that I needed only problem now is the engine size has gone up from 6.3 liters (383) to 8.2liters (502) lol should be fun. Not the way I wanted to go but at £300 for engine and box was a no brainer just leaves me to fab up engine mounts and splice a prop for a complete drive chain . More photos to follow
