I have an 1986 El Camino with a 402 big block. 750 cfm and a mild engine . It's not a big horsepower machine. Probably around 300-400 HP. I am replacing the mechanical fuel pump and wanted to know if there is really a difference between all these different ones you can get at local auto parts stores.
