They should be fine for your app. The stock injectors and fuel rail will support over 500 hp. You will need the wiring adaptors FAST #170604-8. Casper Elec. and some other companies make them also. Using these and the stock rail and injectors is by far the cheapest way to go. I just spent 275.00 on AN fittings and hose for my build. Add 180.00 for the rail, plus 380.00 for the injectors the cost goes up and up. I went with the Fast 57 lbs fwiw. Dual 6 an feeds into the rear of the rails and dual 4an out the front for N2O fuel.
Just run them at 58-60 psi. Thats how GM rates them.
