we just built a 454 small block for our rear engine dragster, it has a magna flo 500 pump, called Rupert carbs to buy our carb, 1st thing he asked was what type of pump, i said electric and told him the size of pump and lines, HIS QUOTE WAS IT WILL NOT SUPPLY ENOUGH FUEL, YOU WILL NEED A BELT DRIVEN PUMP, so with that said we did in fact go to a belt drive pump. will a electric pump work, sure, will it give your engine all it needs? try your pump and see, maybe yes and maybe no.
