I would try a new camshaft designed for use with your computer. A set of roller rockers would help to. Also chips are an easy horsepower adder. Another thing that will liven your truck up is a gear change. Your truck most likely has 3.55 gears. A set of 3.73 gears are a good all around gear but will give you a much better hole shot. This is just my opinion though. Hope it helps.

Pulleys, open element filter and bump the intial timing up. This mods are simple, inexpensive and produce noticeable gains. Gears will also help on the low end as well.
Roller Rockers are great for the valvetrane...you might pick up a few HP...but that's it.

Yeah be careful w/ a high mileage motor...MSD ignition would be good. I'd stick to basic bolt-ons...forget any internal engine mods like rockers or cam. Save your money and put it into a new engine when that one dies. Atleast with the MSD you can switch it to another motor if u get a new one later on.

on one of the engine stands is a 97 XXX block .030 over, 3.25 nodular crank, forged 5.4" rods, 9.6:1, E303, roller lifters and rockers, gtp40 heads, 24Lb injectors...Im projecting 275-285hp with the stock intake, closer to 320 if I run the edelbrock, all on an SFI ECM into my existing perf exhaust.
