hey guys i have a 85 with a 83 flat tappet 302 in it. i just put on a set of windsor sr heads on it, it has a weiand stealth intake, holley 600, mac shorties, off road h-pipe, mac pro dumps, and some kind of cam in it (i don't know what cam but it seems bigger than my friends e cam. it has a c-4 with a stock stall in it, and a 8.8 rear with 3.73's. when i give it full throttle, off idle to 4000 rpm is o.k. but after 4000 rpm it feels like a turbo kicking in and it takes off like a bat out of hell. the guy i bought the car off had the cam put in so i have no clue what cam it is. i want to put a stall convertor in it, this car will see the track alot and will only come out to play on weekends, what stall do you guys sugest?
