The father and son team at Horizon Motorsports spent 15,000 hours creating “Hammerhead” 1973 Pontiac Trans Am for time attack racing. Sitting nearly 28 inches back is an all-aluminum LSR V8 built by Late Model Engines capable of 2,000 horsepower. A pair of Garrett G35-900 turbochargers in the back of the car feed charged air through tubing in the cabin to a reversed intake manifold with two throttle bodies. The drivetrain uses a torque tube to send power to an Xtrac six-speed sequential transaxle from a 2000-2002 IndyCar. Horizon Motorsports fabricated a custom tubular chassis with an IndyCar suspension using Ohlins adjustable coilovers and Brembo eight-piston brakes. A set of Michelin Pilot Sport slicks are mounted on Forgeline TA3R wheels (18×10, 18×14).
