5.0 Liter TBI injector differences

[edfiero1]

I had 4.3l (43#) injectors in my project engine, and it was hitting 100% duty cycle on the injectors so I decided to go up to ones from a 5.0 liter engine.

I ended up ordering ones from 82/83 Camaro. I put them in tonight and am having trouble with getting the engine to run right. I adjusted the BPC and the VE tables, but its turning out to be a lot harder to dial in than I expected.

I just came across the fact that the 5.0 liter engine in the late 80's and early 90's trucks has a different part number for the injectors from the 82/83 Camaro.

Does anyone know what the flow rate of these Camaro injectors is? I thought they were around 55#, but perhaps I was wrong.
What other difference may there be in the injectors between the Camaro and the trucks?

Thanks.
