I would recommend the Carter P4070,they are not noisy like the Holley & Pro-Comps'.No matter which one you get buy a wiring kit with relay and a good filter to go between the tank and pump.Speedway tells you not to use a paper element filter,Good Advise! I found out the hard way,junk Fram's paper element sucked into inlet and burned up a new Holley pump in less than 2 hours
