can't speak to the 302 since i don't know much about ford v-8's, but i'm putting a t-5 behind a 350 in a 39/42/46 (it's a mixed mongrel of a truck).
from what i've learned about the swap so far, the combination of parts you should be looking for will be a "world class" T-5 (it's a later version of the T-5 that has better bearings and other internals) out of a v-8 car like a camaro, and a junk s-10 transmission that has the shifter further forward on the tailshaft (otherwise, it lands in the seat). if you're running a mechanical speedometer, you'll have to find an s-10 trans with a mechanical speedo, and move the gear up on the shaft coming out of the camaro box.
it's a relatively straightforward deal to swap the tailshaft housings. I'm going to run mine with a hydraulic clutch actuated by a wilwood pedal, master, and slave cylinder.
