That big ugly square box that lets air into the throttle body, take it off and replace it with a piece of round pipe. I used some drainage pipe I had. Inside that box the hose goes down to like a 1 1/2".
Replace the cat or run a piece of straight pipe. The cat on those trucks goes in 3" narrows down inside the cat to like 2" maybe 1 3/4" and then comes out 3 ". I added a high flow cat and WOW what a difference. For $79 it was worth it.
K&N air filter.

Buy a timing light and try about 6* more timing. Those old 350s are timed pretty conservatively for towing and hot summers. More timing advance will give quicker throtle response which will feel like more torque. If it starts to ping or wont rev to top rpm take your foot out of it and move the timing back. I found it's the only mod you actually feel until you're talking cam, heads, etc (expensive stuff).

1) Open K&N filter assembly-$80
2) Headers(doesn't matter shorty or longtubes....anything helps a lot)-$300
3) High flow cat and free flowing exhaust-$310( I went with an Edelbrock unit and it was $265 plus $45 for the high flow cat)
4) Jacob's ignition system with ultra coil....helped a ton on throttle response and mpg-$Can't remember....seems like $400.
5) With that many miles on your engine, it coming down to a freshen up period....new valve springs, piston rings, etc-A cheap rebuild can be had for less than $1500.
6) Gears...from my 3.08 to 3.73s were night and day differences-$500
7) Electric fans, felt more torque off the line and it reved a little quicker-$300.
Hope this helps.

He would need to convert if he wanted too but I would do a rebuild at the same time.
