There is a long list of mods and parts. I didnt print it out so i lost it and it will take a few days to get another copy. It's a ALL motor car right now but the engine was built for nitrous. I dont have a kit for it yet but after the motor is tuned i plan on spraying it. The exhaust is 1 5/8 long tube headers...prochamber and 2 chamber flowmasters dumping at the axle.
