Do the 1994 and prior diesel bell housings match any of the gas engines?
I have 460, 300 and 302 as possible swaps if the diesel in an F350 I'm going to explore buying is too expensive to fix.

 

None of the gas motors fit a diesel bell housing.
pre 94.5 IDI 7.3 and 6.9 diesels do interchange completely.

 

Thanks for the info!
Second question, are the input shafts such that I can use a gas engine bellhousing with either a standard clutch or mixed parts?

 

Rephrase that question please.

 

Not sure how much you're trying to swap, 4spds will if you change bell housings. That's about it though.

 

Rephrased:
I don't mind swapping both engine and transmission, but if the stock box behind the diesel can be adapted to the gas engine with just a bellhousing/misc. parts change I'd prefer that. It would be in a wrecker or rollback (checking various leads now) so not having to come up with another PTO would be a plus. I haven't worked on any of the (gas or diesel) 5-speeds so I'm not familiar.
Thanks again for the replies.

 

If it is the 5-speed, you will have to change the tranny too, as it has an integral bellhousing (built into the tranny case) and the gas and diesel bolt patterns won`t interchange. If it was a T-19 4-speed, I think you would be all right because the bellhousings are removable and ?should? interchange. I have a 1986 F350 with a 460 transplanted in place of the 6.9 by the previous owner. I am assuming he just swapped bellhousings on the 4-speed T-19 tranny but I haven`t looked into it.

 

A gas T19 has a much lower 1st gear than a diesel T19.

 

Not all of them do, there are three T19 gearsets, and you will find all three in both applictions, the 6.32:1 first gear one is more common in 460 apps however.
