I have a few questions about some fuel injection. I want to do a few things to my LT-1 like... a cam change (cc306), Long tube headers w/true dual exhaust, a 2,800 to 3,000 stall, and some mild head work. Then a set of either 3:73's or 4:11's.

What I am having trouble figuring out is... what injectors? What lb/hour? What fuel pump? What throttle body? What mm of throttle body? Stock TB is twin 48mm.

I know this is a chevy and all, but hey... I figure that it can't be all that much different.

Cams and exhaust aren't going to make your engine drink that much more fuel. I'd bet your stock injectors and pump will be fine unless you're planning on a blower way down the line. You could just port your twin TBs out to 50-52 mm also. That'd put more air into the engine.

In the calculators section, at the bottom, you can input your expected horsepower and find a suggested fuel injector size.

Cool thanks guys. I'll try out the calculators!
