Engine Masters: 4x11

Big-Inch, Big-Power, Big-Block Manifold Shootout

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.
