NASCAR Classic Series FIRST Race: Vintage Stock Cars Officially Home! (VIR Road Course)

Watch on YouTube

What happens here

The engine chosen for this classic NASCAR road race car is a Cup-spec Bill Davis motor, which is capable of producing over 700 horsepower. This specific engine uses flat tappet lifters, a requirement for NASCAR Cup series cars during its operational era, distinguishing it from Busch and Truck series engines that utilized roller cams. The powertrain is completed with a Mid Valley single-rail transmission, a modern component that was successfully installed without issues despite being newer than a period-correct unit. Current-spec headers and exhaust components are also integrated to optimize performance and comply with modern racing standards.

Goal: Install and configure a powerful, period-appropriate engine and compatible transmission.

Tools and materials

  • Cup-Spec Engine Bill Davis — Providing power to the car, selected for its performance and historical relevance
  • Headers and Exhaust — Exhaust gas management, ensuring proper flow and sound levels
  • Mid Valley Transmission Mid Valley — Power delivery to the drivetrain, chosen for its efficiency and compatibility
