1. you'll need V8 motor mounts and frame mounts
2. you'll need a T5 conversion crossmember
3. radiator outlets are on the wrong side
4. you'll need to lengthen your engine wiring harness
5. need to re-route the fuel line to avoid exhaust heat
6. you'll likely fidn that the driveshaft is too long, I had to shorten mine an inch
besides suspension, brakes, and rearend that should be most of it.
it'll work if you rig up some kind of crossover. The water pump outlet is on the drivers side of a 79 302, your radiator should be a pass side outlet on the bottom. I tried that for a while and it always leaked, so I switched to an early 302 front dress with the pass. side pump outlet. You could have a radiator shop put an outlet on the correct side of the radiator, but why bother with a 6 cyl radiator that won't cool a V8 anyway.
There are always lots of little things that pop up, just don't get in a rush and do a hack job. Its always better to do it once and do it right.
