Help Needed Swapping a 300 "I" 6 for a 95' 7.3

[Diesel1050]

I want to swap the 300 straight six gasser in my 89' F-250 for a 7.3. Found one out of a 95' F-350, and want to know if the current trans will bolt up? Its a 4 speed with overdrive. Thanks!

You will need a bell housing that bolts up to the 7.3. I am not sure the tranny will handle the torque. Get the 5 or 6 speed that goes with the 7.3 to SDD!

Well that's half the question! We're getting some where! Glad to know the 89' has a tranny with a removeable bellhousing. If it helps, the F-250 has a manual trans, with 1st,2nd,3rd,4th, and "D" (Overdrive)? And the transfer case shifter lever is on the floor to the left of the tranny shifter. It should be a Borg-Warner T-18 right?

Well, I don't know about the gassers, but the diesels had the zf. Which has a non removable bell. I know it was offered on gassers also, so may want to check.

It has been a while since I owned my 7.3. Yes it had a ZF and it was one piece housing. Sorry I didn't remember that. Diesel engines usually have SAE numbered housings (1 or 2).

And FWIW ? I'd be sure there's enough suspension and frame work under the 89 to support and.... take the weight of a 7.3.

Purdy good model year verses engineering spread there ?

What tbe heck is "FWIW"? Definitely should be enough frame work, it's going to be lifted about 12", and I have some frame reinforcements planned.

So is the ZF the same bolt pattern for gassers AND diesels?

"For what it's worth"
And no, the zf has 3 bolt patterns. Small block, big block, and diesel.

So this mist have a ZF. The case is 1 piece. Now the question, do I have to find a different tranny to mate to the 7.3?
