Default LS3 42lb injectors work for my set up?

FAST 92mm intake a TB on a heads/cam LS1.

Wondering if the LS3 42lb injectors will work, or the Ford Green Top 42lb injectors better?

I know it's silly, but don't really want anything Ford made on my car.

That's silly, ford injectors are Bosch, same as the ls3. The ls3 are 36lbs at 43.5 psi and the green ones are 42 @39.5 so in our rails they are 42 for the ls3 and 50lbs for the green tops. Your intake will need adapters for the ls3 and so will your wire harness. FYI half you car is Mexican anyway since most of the parts are made there. A Bosch injector is still the best.

The ford green tops are Bosch Design II, and are 1980's technology, the LS3 is the Bosch Design IV which is the absolute latest in injector technology
