565ci Twin-Turbo Big-Block Chevy

Scott Lowry, Festus, MOIt's a horsepower jungle out there, and the biggest carnivores are sometimes cloaked in fiberglass and steel. Scott Lowry had an itch to go fast, so he built an awesome all-aluminum, twin-turbo 565ci Rat to fit between the fenderwells of his '57 Chevy. What you don't see in this photo is the monstrous water-to-air intercooler package that takes up the entire right side of the cockpit. He needs it because it takes a lot of water to cool the pressurized inlet charge that makes 2,800 estimated horsepower. That's an estimated number because the one time he tried to measure the power on chassis rollers, the dyno spit out 1,500 rear-wheel horsepower with a tweaked torque converter. The lure of turbochargers is that it doesn't take a wild combination to make lots of power, so you might be amazed at the mild compression and cam specs. Lowry's biggest hurdle now is applying all that power to the ground. The '57 has run a best of 4.60 at 160 mph in the eighth-mile. That, friends, is equal to 7-flat in the quarter. All that with only a 3.70 rear gear.
