Gary Bowman likes horsepower. He also likes horsepower in lightweight cars where the power can be the most effective. Gary’s last E-ticket ride was a Backdraft Cobra replica with a Ford Racing 427ci Windsor stroker pumping out 550 hp at the crank. It was fun, but he tells us it just wasn’t enough to scratch that itch. No, he wanted more power, or in his words, something “rowdy.” It would also need to be low maintenance, and run on pump gas, too. It just so happened Gary had a new Backdraft Cobra replica on order, and an empty engine bay to fill.
Enter Brent Lykins at B2 Motorsports. We’ve followed along with several of Brent’s engine builds in the past so it’s no surprise to us that Gary sought out Brent to build what essentially boils down to a race-spec engine, detuned to run on 93-octane fuel and not require constant maintenance—a staple of race engines which are regularly torn down to replace wear items each season. This meant no “spring eater” cam profiles (as Brent calls them), long service valvetrain parts, and simple, yet effective carburetion.
Brent’s foundation for this street-spec race engine would be one of Dart’s 9.5-inch deck SHP blocks with a 4.155-inch bore. Coupling the monstrous bore with a rotating assembly consisting of 6.250-inch long Oliver billet rods swinging on a Callies Dragonslayer crank with a 4.100-inch stroke nets 445 cubes of “oh my God!” Topping the engine is a set of custom-ported Trick Flow Twisted Wedge Race 225 heads and an Edelbrock Super Victor with a Quick Fuel carb. The valves are actuated by a solid roller cam with 0.700/0.690-inches of lift. Brent calls it a hybrid street/race build. We simply call it 662 hp of Ford small-block heaven! Check out the build in more detail on the following pages.
