So you've got an LS and you need to make a choice on an intake. Chances are high you're looking at some version of Holly's "Ram" Intakes, whether it's the long runner Hi-Ram, the Mid-Rise, the compact Lo-Ram, or the hood-clearance-friendly Ultra Lo-Ram. On this episode of Engine Masters, presented by AMSOIL, we line them up one by one on our 550 rectangle port headed 6.2-liter LS to help you decide which power curve is best for you. But fear not, cathedral-headed LSers, this test applies for you, too!
