There is a very nice, but very long, Father-Son engine build project on Thirdgen.org:

If you plan to keep the TBI than aim a lot lower than 360 fwhp. The truck will run very well with 260 fwhp (it'll run 15.0 in the quarter) and more importantly it will run forever with very low maintenance, it'll have awesome off-idle torque, and it will still get "decent" mpg for a truck with a 350.

The most imporant thing you can do for that 92 TBI engine is to remove the heads and port them.

The second most important thing to do is add dual exhaust (with cats) and with low restriction mufflers to the truck -- even if you have to keep the iron exh manifolds (if you do, port them too).

Those two modification will bump the engine output to 240+ with no other changes than raising the fuel pressure.

Do a port cleanup on the factory aluminum TBI intake manifold and pay more attention to the outlets at the top of each runner, and do more porting work on the lower plenum runners because they are more flow-impaired than the upper plenum is. Also port the base of the intake under the TBI.

Remove the heavy rotators on the exhaust valves and replace them with Caprice/Impala LT1 350 retainers/locks and you may as well use the springs from that engine too, to replace the valve springs on your engine. All GM parts, all inexpensive.

On the cam: you have a choice here -- either keep the stock cam which means you will give up 20+ fwhp but have an immensely pleasureable engine to drive with, or do a cam swap to gain more power but give up something on the lower end and on part-throttle driveability. If it were me, I'd keep the stock cam and use a set of $80 1.6 ratio self-aligning stamped steel rocker arms from Scoggin-Dickey..... and then let dad see how he likes the engine. If he wants more, you can always do the cam swap later.

The last item is that depending on how far you go and IF you keep the TBI, you will probably want a custom chip (EPROM) to go into the ECM (computer). So you would need the entire wiring harness + ECM + TBI to use. Carb-to-TBI swaps can consume an entire thread, so I won't detail it here. There are posts on Thirdgen.org that do a better job covering the subject than I could. HTH.
