Owned by: Matt Thun, Olathe, Kansas

Mopar Power

Engine: Matt swapped in an '08-vintage 5.7 Hemi with help from Street & Performance (computer and wiring harness); Lokar (throttle linkage and trans kickdown cable); Glenn Baugus (who supplied the engine); Scott Shanks (source for the K-member); plus Dusty Fisher, Mike Johnson and Denny Holstrom (engine removal and installation help). Custom "Hemi" engine covers by Performance Contracting, Lenexa, KS (with carbon-fiber print finish by Dynamic Finishes, Kansas City, MO). Radiator's a 26-inch BeCool aluminum one with twin electric fans. Speedway Muffler in Kansas City, KS installed the exhaust system that includes tti headers, 2 1/2-inch pipe and Flowmaster Series 50 mufflers.

Transmission: 727 Torqueflite rebuilt by Olathe Transmission, Olathe, Kansas. Shifter is the OEM console-mounted Slap Stik.

Rearend: Original 3.23-geared open differential/pavement-striper

Sure Grip

Suspension: Restored original '74 'Cuda--heavy-duty longitudinal torsion bars, front and rear anti-sway bars and rear leaf springs--plus Monroe "GasMatic" shocks at all corners

Brakes: Wilwood slotted-and-drilled 4-wheel discs, power assisted

Wheels and Tires: Billet Specialties' SLG 23s (17 x 7 inch front, 20 x 8 1/2 inch rear) wear Nitto 555s (235/45R17 front, 255/45ZR20 rear)

High Impact

Body: Restored original '74 E-Body unibody wears all its original sheetmetal, plus its OEM vinyl top and side stripes. Bumpers are Keystone repro '70 Barracuda ones, while add-ons include fiberglass front/rear spoilers and aluminum rear window louvers.

Paint: Single-stage Rallye Red acrylic enamel (sprayed on by a previous owner) still looks great
