More information on exactly what he wants the truck to do would help us point you in a more defined direction, rather than just throwing out suggestions.
You mentioned 400 hp. OK, but doing what in the truck? I can build a 400 Hp 289 or a 400 hp 7.3L. They are going to have very different uses.
I built my 352 to pull a 4500 lb plus wagon down the road at 70 mph all day long, in OD, with minimal effort. That motor put out 325 HP, 375 ft-lbs on the dyno with a very flat torque curve that comes in at over 300 ft-lbs as low as 2500 rpms, perfect for a highway cruiser.
A bit more cam and compression, and that engine would be very capable of 400 hp, but I would likely be moving the torque curve up higher into the RPM range as well. Which would work well in more of a stop light bruiser application. Throw some more stroke at it to lower the rpm range of the torque curve and you are back in the good pickup motor that can tow category.
Lot's of Options, which is why a good plan is critical.
