Holley electric fuel pump

With 300 hp, a 600 cfm carb, and the stock 5/16" fuel lines a holley electric pump is probably overkill. I've been looking at going that route with my 400hp 340 build, 3/8" lines etc, and from what I've been told its overkill for me. I'm going to go with a hi-volume mechanical pump. No noise, no wiring, easy. Holley's are good electrical pumps, but other than a slightly cooler fuel charge you're not gaining much. If you don't have a vapor lock problem I'd stay mechanical, especially for a street driven car.
