It took Madison, Wisconsin's Ringbrothers 2000 hours (and doubtless trips to Johnny Delmonico steakhouse) to slap together this 1967 Mustang show car — a commission whose intent is to win the 2007 Good Guys Street Machine of the Year award. The metallic green creation's been dubbed "Reactor," and includes split rear window glass, carbon fiber deck lid, hood, front fascia, front and rear bumpers and tail light panel, and an interior designed in a "sleek, European style." Under the hood is one of Roush's 427 IR crate engines, which generates 552 horsepower and 535 lb.-ft. torque, by way of forged pistons, rods and cranks and race-ready block. For those who geek on details, the reactor's build book, including photos, will be published in February. – Mike Spinelli
