I have a 91 coupe with an AOD. The car came with pullies, smog delete, shortie headers, o/r H-pipe, adj. fp regulator, electric fan, HD radiator, msd distributor, 3:73 gears, and welds. I've added a msd 6al, mac pro dumps, guages, cowl hood, shift kit, ATI balancer, trunk mounted optima battery, 70mm TB and an typhoon intake. So what should be next? I know i need heads and a cam but don't want to do that kind of work to a car with 130g on the odometer. I have a nitrous kit but i'm a little nervous about putting it on. Should i go mass air and injectors, fuel pump, converter and input shaft, or..........?
