More power from my 360 Duster?

Your combo is pretty decent but not really a quarter mile pounder, i would reccomend a comp cam from the Xtreme Energy series or a Voodoo cam just as mentioned before and get some headwork done to get some more power out of it. But since you need something quick and i dont know how much money you have in your budget, if it were me i would buy some Mickey Thompson ET Streets. what tires/size do you have on right now? If traction is an issue i would go with these tires, if it is not i would buy a Holley Street Avenger Carburetor probably a 675 its very easy to tune and maintain.

P.S. Be careful though i wouldnt reccommend driving daily on these tires especially on the freeway, buy two cop car style wheels for like maybe $50 bucks on craigslist and i would get them mounted and balanced at a shop and whenever you go out to play put em on and when your going to drive around town swap the street tires back on.
