Taking the 3.4L out and dropping the LT1 in. I am worried about the fuel pump though. Does anyone know the pressure put out by the two different pumps. Eventually i need to replace it anyways because it has 135k miles on it but will the v6 provide enough fuel at least for a while. thanks

 

I *believe* that all 4th gen f-bodies use the same fuel pump, regardless of engine.

 

Though the pumps are not the same part number, I seem to recall that those that have done V6 to LT1 swaps have had no problem. The V6 engines have the same fuel pressure requirements, so the pump should deliver the fuel fine.

 

I did a lt1 swap and am still using the v6 pump with no problems. The pressures are the same.

 

ok yeah i knew they were different part numbers but as long as the pressures are the same then ill be fine. Eventually im gonna put a new one in but it will work for now. Thanks
