How much fuel pump power does your motor need? This time on Engine Masters presented by AMSOIL, we investigate the limits of four budget, mechanical pumps on our very streetable, 500 horse 372 Chevy. Can these budget pumps keep enough pressure and flow to support our power numbers? What about the power that you're making? If you're anything like us, this might motivate you to take a second look at your own fuel system.

This time on Engine Masters presented by AMSOIL, David Freiburger, Steve Dulcich, and Steve Brule´, go on the hunt for the best manifold to make big horsepower numbers on a big-inch, big-block Chevrolet. These aren't manifolds for any boring, old 454 or even a 496. We're talking 598 cubes of big-block, and we're throwing four different single-plane, single 4bbl manifolds at it from Dart, Pro-Filer, Brodix, and Edelbrock to see how the difference in their runner walls and plenum shapes make or cost power.
