Electric vs. Mechanical Fuel pump debate

Got a 70 Dart, 340, 750 vac secondary, light spring, 4 spd with 3.91, 25 inch tires. It's drives like 4.56's because of the short tire. Car tore up a friends that runs 13.60's.

Has a stock fuel pump from Kragen and 5/16 line. Runs to 6200, normal shift points are 5800. Never runs out of fuel even at 6200 in 4th gear. I have a holley mechanical pump if needed, never saw the need to install it. Car is going to get a Proform 750DP for a test.

Personally I wouldn't spend the coin on a fuel system unless there is some need. I've seen lots of people say they are running out of fuel and it was a totally different unrelated issue.

If you aren't upgrading the fuel pickup/sending unit, it's a questionable upgrade at best. You still have a restriction right out of the tank. Don't know what's in the summit kit.

If it ain't broke, don't fix it. That's my two cents.
