Auto or Manual? With a manual, those numbers can be seen with a 35/40 hybrid or Super B turbo, timing, AFC mods, and a 4k GSK. Stock injectors with a 215 pump are capable of it for sure.
Cost would be however cheap you could find the turbo, and buying the GSK. You can time it yourself, and the AFC mods are free if you own a grinder and screwdriver. And unless you plan on o-ringing the head, play it safe and only go to about 16* timing.
Auto will require more motor mods, as well a stout converter and valvebody like already mentioned. But either pump is plenty capable of those numbers with relative ease and low investment.
Biggest investment with a truck used for pulling and racing is the transmission for the power level you're talking. A good dual disc clutch and upgraded input will be necessary for the manual. A good triple disc converter, billet input shaft, billet flexplate(if rules require sfi rating), and valve body for the auto.

Not that I recommend it, but you can get one to lope by setting the governor springs one or two clicks looser, if it's a 4k. Really getting it to lope would require a well setup, high flowing pump, larger lines and large injectors. IMO, don't do it, but it is your truck.

a 24 valver can lope easily by installing oversize injector tubes and lines .084 lines and .120 transfer tubes
For the P-7100 .093's are ok on the street,lope a tad bit and loose a little power on a dyno and make daily driving a bit more interesting.The .120's are a real PIA on the street,kill dyno numbers and the constant loping makes daily driving a challenge,however,if wide open throttle is where you run they will make the best choice but thats not me.

12v cummins
it all depends on what class he wants to run. depends on your area. in my area 400hp would not cut it to be competetive.
