hi.........i have an 87 iroc, tpi, soon to have a 350, and right now i have a 305, th-700r4 b&m transpak rebuilt, and rebuilt slip posi 10 bolt rear 3:23 gears. with this engine i have bigger fuel injectors 24 lb, adjustable fuel pressure regulator, holley fuel pump inside tank, msd ignition without box,,,just msd distributor cap and rotor and blaster coil and super conductor wires, edlebrock combo runners and intake, modified ram air that is posted on this site on how to make it for the tpi....k&n airfilters. i wanted to know from anyone that uses nos.......i just want a simple 50 to 75 shot of nos (filled bottle) and the kit not to be complicated. i also wanted to know if these mods are descent for nos for air and fuel take in. not goin to be running nos all the time just once a year to the track....i also have a book by david shelby that gives a kit but no part number that actually this kit deals with a dual prom chip that switches from the stock to the nos prom when in full throttle. that kit seems nice but says that one is made for the speed density system but i just have the MAF SENSOR....and would like a similar kit but if not does anyone know of a good kit to use. can afford 600 to 700 dollar kit...hopefully thats enough. any good tips...can greatly help me out and im descent with wiring and electrical knowledge. i see some camaros with nos and they run them on stock engines with little or no mods if any..can i do this..i just want to put it in the car and have fun on the track for a day. thanks to anyone that can help. sites are good to for kits if you guys can give me. if anyone needs to know of more mods let me know. just thinkin is the nos kit 5151 a good kit....cause i heard bout that one a few times....ooppsss forgot to mention i have a fuel exhaust system headmen headers, high flow performance catalyic converter, and flowmaster exhaust system all the way and hypertech chip street runner as well.:hail: :hail: :hail:
