Most on this board have newer trucks.

If you stick with the 2.9L.. I'd do a basic overhaul but with the following:
Have the heads ported and put in some hardened exhaust valve seats.
Have a custom cam gound to match the heads
Port out the stock manifolds.. or go with a set of headers that are slightly larger primarys than the exhaust port measures.
Then step the injectors up one range and get a tune for it all. (of better yet a dyno tune)
This is a simplistic approach but very effective if your not seeking higher than stock rpms.
Too many people go waaaay too big on one or two things and wind up being very disappointed with the outcome. Just tweaking stock parts and then a matching tune can net a very good bang for the buck.
