    Ditch the 4.3 and get a 5.3. There is no such thing as cheap when it comes to power and speed.

    lol well you asked for mods to soop it up. I said cam, or some kind of power adder. You wanted free, and like said above, theres nothing really free to make your friends truck faster. lol i dont know what answer your looking for?

    Nitrous is a cheaper than most and to make it faster

    If you want suggestions for what to do to a 4.3L engine, why don't you look for a website that specializes in 4.3 V6 engines and ask the question there? We specialize in LSx based engines and engine swaps, hence the name LS1Truck.com.
