F250 Trans

[EOGeer]

I have a 90 F-250 with a straight six n a manual trans. Want to put a 7.3 under the hood.
My question is will it bolt to the trans as is or does it need to be modified or just changed out?

I'm not 100% but I would certainly think that you will need a zf5 or zf6 which ever one you want but I seriously doubt that your tranny will bolt up, if and thats a BIG IF, it bolted up I doubt it would take the torque that the 7.3 puts out, so I would find a zf5 or zf6 and eliminate any doubt.

Trans won't work. Need to find a trans from a diesel.

Thanks that's what I thought but was wanting to make sure.

Diesel trans have an integrated bellhousing unlike the gassers.
