Re: vortec 454 injectors
Second the Five-O-Motorsports ones. Do NOT buy ebay injectors if you plan on keeping the truck for any length of time, they are garbage, been there done that. Also avoid the "OEM replacement" injectors, the fat body original style injector (rochester design) is just trash. The Bosch-style injector is a much better design and has a much lower failure rate. You can *sometimes* get away with dropping LT1 injectors (Bosch style) into a Vortec 454 without setting any codes, they are 24lb/hr vs 19lb/hr (454) of fuel delivery.
