A 1955 Chieftain won a Goodguys award.
The judges didn't see what was coming.
They found out under the hood.
In 1955, Pontiac retired a 22-year-old straight-8 and introduced its first overhead valve V8 — the 287 CI Strato Streak. It was a landmark moment for the brand. The Chieftain was the car that carried it.
Motorworks of Spokane answered with something different. They built a 509 CI roller V8 with custom steel heads. An Edelbrock RPM Air Gap intake feeds a Holley 850 cfm double pumper. Rated at 623 lb-ft of torque. Custom headers exit through 3-inch side exhaust with Flowmaster American Thunder mufflers. Custom engine and body mounts were fabricated specifically for this frame-off build.
Underneath, Fat Man Fabrication Stage III front suspension up front, TCI 4-link rear with Panhard bar and adjustable coilovers out back. Dutchman 9-inch rear end with 3.55 gears and 31-spline axles. Power steering and power brakes. Air conditioning and heated seats. Black leather interior with power doors and windows. Red and Black with flame graphics over smoothed one-piece bumpers and frenched halogen headlights.
Goodguys gave it an award. Pontiac Enthusiast put it in the magazine.
The 509 made the argument. The judges just agreed.
