i was wondering before i spent the money, will corvette/camaro ls1/ls6 fuel injectors fit my 2004 avalanche with a 5.3 without new fuel rails or a injector harness. i am planning on building or buying a used supercharger setup and will need bigger injectors, anyone know what flow rate or lbs/hr i have stock and will need with roughly 7 to 9 lbs of boost. thanks
