Freiburger's 582 big block Chevy is back! And this time we're using it to shoot out 1050, 1250 and 1450 cfm Dominators. When you're flirting in that 1,000-hp range, how much difference do those extra cfms make, and how much does the tune change between them?

Does a 300 shot of nitrous sound like a lot, or like you're just getting started? That's one way to tell if you should be running a plate or a port system, and the guys walk you through each system, how much power you can add through each, and the jetting differences between them.
