Engine Swap

Hey Guys, I'm sure there's a post here somewhere regarding this but I still haven't figured out how to productively search for such threads so my question is, what's involved in getting a 460 in an '84 250 (currently a 5.0L with 4-speed). What I need specifically is what mounts would I have to use, does a 460 bolt up to the 4-speed... basically, what's needed to adapt the 460 into this bay.

Thanks!

Motor mounts should be different but what transmission does the truck currently have?

I wanna say it's the T170FT. For motor mounts, wasn't a 460 offered as an option that year? Can I just buy mounts for a 460 and they should bolt right up to the mounts welded to the frame?

The transmission you have will not work with the 460. You should be able to just buy motor mounts since yours is a F250.

Was the 460 offered with a manual trans at the time? If so, which was it?

ZF transmissions were put behind the 460 motors. Do a search and you will find some very useful info about the zf5 transmissions.

You could most likely get a combination that would work with your tranny, but that tranny is very weak, it would never hold up to a 460. What are you planning to do with this truck? Like the other poster alluded to, you need a heavy duty tranny for that engine. They came with t19 4 speeds, if you want overdrive a zf 5 speed would work.

You are correct, if you have a f250, you should be able to find the plates and mounts to mount it up from another f250 or 350. But you may have a small problem; The trucks that came with the diesels and the 460's have a big dent made into the front crossmember for oil filter clearance. If you have a small block f250, then your truck probably doesn't have this dent, and you will need to run a remote filter setup. Even with the dent,, the 460's had a special oil filter adapter different from the cars.

You will have to check your radiator support. See if it will accommodate a 460 radiator. It may not and will have to be changed, not sure though.
