I know my 97 was a dog until Nelson tuned it, then it came alive, for a 4.3 that is. They can be decently quick for what they are. Tell him he may want to look into the marine intake swap, pretty sure those are popular with the 4.3s 4.3L Vortec Marine Intake Conversion Helpfull Hints: - FullThrottleV6.com -- The V6 Tech Source

I had intake, shorties, high flo cats, flomaster, tune, and I went 16.7. I could hang with stock 5.3s
