Thanks for all the replies. Looks like a header and bored throttle body will give me some increase, w/o major expense. Any major mods would be money better spent in a bigger truck. One of these days I'll set this one up for wheeling.

'94 extra-cab 3.0 extra slo (auto tranny) original owner. E/B o/s valve heads and no more crossover. More mods to come.
