the guy i bought my car from put everything in my sig in the car. i havent done anything except a new alternator (which i shouldve got a 3g but couldnt) im thinking the guy had an intention of putting either nos or a supercharger on the car due to the intake manifold, cam, water pump, heads, etc. im not going to supercharge this and im wondering, isnt my manifold and cam made for high rpm's? i was reading about the manifold and it said like, good power over 5000 or something. since im not planning on supercharging or nos, should i go with a differnt cam and manifold? my bro has a lot of the same stuff as me except edlebrock manifold, and tfs 1 cam and some minor stuff and his car seriously is scary compared to mine. what do u guys think, since your the experts
