I'm running a Holley Red 97gph with 3/8" lines and about 550hp right now. I am using a wideband though to monitor AFR to make sure it never leans out. No problems so far. This is ofcourse on stock cylinder heads though. I expect 600-650 with a nice set of heads and i still think the pump will be fine.

Shawn thanks for the info. Yeah I have a Fast AFR meter as well I plan on using. Pretty much redoing the car (had a really old small carter pump on it.

Sounds like a good plan to me......have heard some issues with that pump but who knows if it was the pump or the installers. Everyone seems to love the Mallory 140 which I now have. So far so good. I don't know about the check ball. With an electric pump you have pressure instantly. I went with 8an out of the pump. I liked the idea of pulling on 10an and pushing on 8an at the pump. Your not supposed to use pipe tape either. I ended up having to on the pump inlet. After a couple hundred miles it began to leak sitting in the garage. The rest of the system is teflon paste. The Mallory 140 is right at 110gph at 6 or 7 psi which is perfect for 600hp.

I'm running a Holley HP150 with a Aeromotive 100micron, 10micron XRP filter, and a Racepumps regulator, Xrp dual feed line at the carb and 1/2 stainless throughout the whole system. Works well and the fuel pump isn't really loud. The a1000 is a nice unit and I was orginally going to use one but It needed the return line and I did want that. If your planning on going to EFI later on, it would suit ya just fine. It is loud though.This is one the chevelle powered by a 540, and I have no issues with fuel. G/L
