Magnum Force
Joe Luis, Age: 32, Roselle Park, NJ
Getting the most out of his street car is what Garden State native Joe Luis has in mind, and to that end, he decided to forgo finding and building a used engine and bought a 360/300 horse crate motor from Mopar Performance. His '68 Dart GT is really set up for street cruising; he and his wife drove with us to the Mopar Nats on the Keystone Caravan last year. The Dart, a deal he says he could not pass up, is a followup to a Pro Street Demon project that got out of hand.

Joe and his brother came to spend the day finding out small things about the car. The package is well balanced, and Joe uses a Holley carb instead of the OE-type fuel injection on the car. The numbers he ran, considering the fact that this A-Bomb is all throttle, no bottle, may help us understand why the Magnum engine has been so well-received.
