Friend of mine has a '91 auto reg cab LB. He was asking me the other day what he could add to make more power. He's looking at bolt on power, nothing too serious. Already has Banks exaust (not sure which one) and a pacbrake. The truck has 190k+ on it and he doesn't want to do much that'll jeopordize his transmission. I said the weight he pulls and the high mileage, he's walking on eggshells already. Just thought I'd ask you 1st gen'rs what your thoughts were. Thanks in advance. He was a TDR member long ago.
