Hey I'm new here, I have a vortec 305 that I put in my blazer and I'm running an affordable fuel injection tbi conversion. I use to have a 283 in the truck so now the engine is running lean. Does anyone have or know where to find a bin for a vortec 5.0 to tbi. Stock motor other than I put a jegs carb to vortec intake manifold on.

Thanks

7747 ECM? What trans? Also what injectors? Probably going to need atleast 350 injectors or run around 18-20 psi fuel pressure on 305 injectors. Stock vortec 305 makes a good bit more power than a TBI 305 or 350 engine.

4l60e but I'm running the trans manually so it isnt controlled by an ecu at all. I believe they are 350 injectors on the top of the injector there is a white line and a green line, I know that means something but I cant remember what. Yes it is a 7747 ecu. I'm running the stock in tank fuel pump because affordable told me it would be sufficient but that was for the old 283 I built. I have not changed the fuel pressure regulator but I could measure it to see what pressure it is regulating at. I dont know enough to right my own .bin so I may have to find someone to write one for me if one doesnt exist.
Thanks.
