It's the age-old battle of power v price, but is it as simple as all that? Are you really giving up significant power by cheaping out on a solid flat tappet, or is the extra power of the roller worth every penny? Join us on this episode of Engine Masters presented by AMSOIL as we talk duration, lobe intensity, spring pressures, dollars and horsepower.

Manifolds or Headers for Your Turbo LS?

Are your cast manifolds enough to keep up with your turbo motor? And at what point should you be running proper headers? Those are the questions we're asking this time on Engine Masters, presented by AMSOIL. Using a typical mill you'd find in a turbo street car, we're running our 630-hp 5.3 LS with factory exhaust manifolds and again with turbo headers to show you the differences in boost, backpressure, and horsepower.
