gary are you wanting speed or horsepower? if you just want a higher top end, swap in a taller rear end ratio, a set of 2'73's should get you aproaching 140mph, not recomended in a open bed pickup truck due to arodynamics , if its horsepower you want ie; quicker from a standing start to 100 or so how much power you get basicly depends on how much money you want to spend for a driver that is both quick and reliable swap in a crate engine 383 stroker there cheaper than rebuilding yours once you pay for all the nessassery machine shop work for a good rebuild, that will put you in the 400 hp neighborhood with a little tweeking and manifold and carb set for around 3 grand [ stock '75hp is around 185] and still be a reliable street drivable truck, beyond that the money goes fast as the hp climbs as well as you'll be spending every weekend tweeking your engine also keep in mind this is a pickup with a relitivly light weight rear end, you can only stick just so much hp to the road then you'll just be smokin the tires , the stroker will burn the tires right down to the rims if thats what you want
