Hey guys i was wondering if you could help me out. I bought a 94 trans am recently with a full hooker exaust, longtubes off road ypipe and catback and a K@N cold air setup. Im planning on doing like a CC306 cam and the rest of the supporting modifications for it soon. What im wondering though is, i have a vigilante 3600 stall converter i just got used and was wondering how much faster the car would be in the quarter mile with the rest of the car being stock. I know it wont be the greatest ride but if i got some good drag radials and the 3600 stall with a full exaust and cold air how much faster would the converter make me? I heard i would have to get it programmed too cause of the big stall is that true? Thanx for your opinions.
