been thinking about sprayin....do i need to upgrade the fuel system? well if i ever go over 75? remeber ill have that with the biult high comp stroaker motor, like do i need a safc? walbro fuel pump?, inmjectors? and what about a 50 shot on a stock motor, can u use stock fuel system with a 50 shot?:thumbsup

You can run a stock setup up to a 75 shot. I would reccomend an intake and exhaust. Exhaust for nitrous is just as important as it would be for turbo cars. Replace fuel filter, run some injector cleaner, and keep an eye on the guages. But no fuel mods are needed.
