Any other requirments you have of the truck, a little towing or anything or is it just a toy, daily driver? These Camaro guys like BIG cams there are some "milder" cams that will perform quite well and sound wise will pass for stock. The MAF is not helping you and just makes your tuners job harder consider using a stock one. If your usage is as a toy and includes at most light towing then a stall like a 2800or higher Edge, Vig , or Yank would be a great mod. I have a 2800 Edge in My Caprice and tow a little, it is fine even when I had 2.93, even better with the 3.42s, gears should be on your list if they are anything numerically lower than 3.42. Last time I went to the track a friend of a friend had a 2002 Lightening he ran just a tenth or two faster than me the highlights of my mods are a ZZ3 cam(VERY mild compared to what these guys are talking about) the Edge 2800, and 3.42s, the handicaps are stock exhaust manifolds and 87 octane tuning. We were both on street tires, my 60s were better even though I had traction troubles and he did not, was a good bit quicker for the whole 1/8th after that the boost he had made his HP enough to make him faster than my lowend torque made me. My car is probably a little heavier than your truck and will 60ft. better(b-bodies hook pretty well compared to most other vehicles), a set of headers and I would have walked away from him. Another friend with an Impala stock engine, 3K stall Edge, 3.73s, shorties, 93 octane, some lightening for a race weight of probably 4200lbs. and sticky tires was faster than the lightening all day.
