Can I ask what's the reason you're going away from the stock mechanical unit? Chevy SB mechanical units are known for dependability and they don't require a regulator. They'll definitely keep up with 400 horsepower.
What Glenn said. Mallory pumps are very reliable, don't make a lot of noise, and you don't necessarily have to run a return line to the tank. I run one on my '32 and have had good luck with it. The Holley I had originally puked out after 3000 miles.
