Right but what he was saying was that to get the 318 with the forged crank in later years it had to be a truck with a manual transmission (clutch). I think that was pretty much across the board, as I had a 77 400 virgin engine with a beautiful steel crank and it was out of a 4x4 truck with a manual transmission. I think they did that all the way to the end of the big block's run.....possibly the 318 as well.
