"Using current NASCAR parts under the hood and on the drivetrain was a must, to merge the old racer with the new."--Phil Brewer
Fast Facts
1970 Plymouth Road Runner Superbird (Recreation)Built by: YearOne, Braselton, Georgia
Mopar Power:
- Engine: From Gillette/Evernham Motorsports' engine shop came a current-generation 358-inch NASCAR-spec engine, sporting a big Holley four-barrel, MSD's HVC Pro Billet distributor, coil and ignition box. It breathes out through a custom-fabbed exhaust (incorporating Flowmaster ½-inch oval track mufflers) by Gillette Evernham Motorsports. All engine plumbing by Brown & Miller Racing Solutions, Concord, N.C.
- Transmission: NASCAR-style Borg-Warner T-10 four-speed manual, built by Gillette/Evernham Motorsports.
- Rearend: Ma Mopar's 8¾-inch one (just like the ones that Petty Enterprises ran on their Superbirds). There's a pair of 30-spline axles, an Eaton Sure Grip differential, and a set of 3.90:1 rear gears inside.
Sure Grip
- Suspension: (Front) Magnum Force's tubular K-frame/A-arms and spindles with QA-1 coil overs (Rear) A Year One-fabricated 4-link with a Panhard bar and QA-1 coil overs replaced the OEM leaf spring setup
- Brakes: Big Baer discs all around. How big? Try 13-inch rotors with Baer 6S six-piston calipers--at all four corners.
- Wheels: Aero 59 Series NASCAR wheels, 15 x 9 inches all around, wearing BFGoodrich Radial T/A gForce tires (27 x 10 x 15).
High Impact:
- Body: Original 1970 B-Body hardtop unibody was converted from a Plymouth Satellite into a Superbird by adding a Jannek fiberglass nose cone and rear wing. Remedial body work included replacing both rear-quarters, trunk floor and extensions, and rear wheel wells. Fabrication work was by YearOne's Mark McDonald.
- Paint: Steve Jones at YearOne sprayed on the BASF Petty Blue-over-black color scheme (The Body was powder-coated top to bottom by Miller's Powder Coating prior to paint)
- Interior: Inside the roll cage (fabricated by Mark McDonald) is an interior that's been upgraded with Kirkey racing buckets and a YearOne repro "Tuff wheel" steering wheel. Interior restoration by Henderson Upholstery of Sugar Hill, Georgia
