I just bought a Carter 4601, figure my deal will make 470 to 500 hp. It should be able to handle what you expect for power, as long as you have a good system.
I have had this same pump on my Savoy for about 10 years now and can still run strong. I feed it with -10 from the cell and 1/2" aluminum to the Quickfuel deadhead regulator. Gus
