Last winter, I put a fresh rebuilt 460 back into a 79 F350 4x4. After removing the old motor, I discovered that the original 400 bellhousing had cracked, and been brazed tqice. That housing got pitched. A local slavage yard sold me another 400 bellhousing, even though I specified a 460 housing. When the first 460 was swapped into this truck, a 1/4" thick spacer was made to go between the bell, and the tranny face. I tried leaving it off, and the T18 input bottomed out in the pilot, before I had the trans drawn up tight to the housing. I HAD to use that spacer, unless I wanted to cut a 1/4" off the end of the tranny input shaft. That tells me that the 460 bellhousings ARE deeper, by around 1/4" .
