thanx for the advise guys, how much difference would the ls1 cam make? can you recomend some bolt ons

and the spesific cam i should get, my goal is to get 13's but i know my truck is to heavy and a daily driver

so any recommendation would help alot just to move alittle faster and maybe give compition to the cars my

friends Z28 beats (love the sound of a 01 z06 cam but if something else works just as good with out changing springs,rods,and rockers, i rather do that) thanx
