"I've run across people that don't like that I've put that engine in an older car. To them, it's OK if its period-correct., but they don't like the new stuff."-Matt Thun

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.

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)
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.
