302 to 5.4L swap in a 92?
Ok, my 302 is a bit worn out currently has 197xxx on the clock. All the drive train stuff is the same way nothing has been replaced / rebuilt except the little things, nothing big like the front or rear end tranny transfer case or motor. My question is has any one dropped a 97+ 5.4 into a pre 97 truck? along with the tranny and all the running gear. Any help would be great
-thanks

Dimensionally, it will fit just fine. It's almost the same size as a 460 which fits very nicely in the 87-96 body styles (and an option on the F250/F350).
I'd recommend swapping the engine, tranny, wiring, computer, accessories at the same time, making the swap easier. You'd have to make motor mounts, which is not really a big deal if you suspend the engine/tranny with a crane and mock it up while it "dangles" over the engine mounting ears on the frame.
If you want to mate a 5.4L to your tranny, that's much more work as the bell housing patterns aren't even close.

do you know if both the front and rear ends will bolt up?? are they the same size?

Bolt up to the driveshafts, or to the frame? The rear is a solid axle, that's easily adapted if necessary. The front, honestly, I've not looked close enough to be able to say yes or no.
When I saw your post, a friend was here with a 5.4L F250, so I roughly tape measured the engine then measured my older 93 F350 and saw that it should fit no problem. I glanced around the engine compartments and didn't see anything obvious that would prevent this swap.
I'd swap the new engine/tranny in, and leave the older suspension, driveshafts, and just worry about mating the two with u-joints... this way the shalfs are the right length and so forth. But that's just me, after a 10 minute tape measure session.
