I don't know. Like I said, "one of us" used a different style Autolite carburetor. I'm tellin you from first hand experience I've run one before on a slant 6. Obviously, the one I ran was different than the ones he's talking about, because it fit. The bad part is, I don't remember WHAT it came off of. I THOUGHT it was a 300 inline six, but I'm not 100% sure. This was when I was in high school auto shop. I was 16.....17 that was a while ago.
