📖Generation guide
First Generation (1968-1970) • 1968-1970
This era marked the launch of the budget-muscle segment, with the Road Runner featuring a standard 383 Super-Commando V8. Optional engines included the powerful 440 Six-Barrel and the legendary 426 Hemi.
Superbird (1970) • 1970
Designed for NASCAR homologation, the Superbird featured a distinct 19-inch nose cone and a 24-inch rear wing. Available in vibrant colors like Plymouth-Petty Blue and Limelight, only about 1,920 units were produced.
Second Generation (1971-1974) • 1971-1974
The fuselage-styled Road Runner retained its muscle car essence while adapting to emissions regulations. While the peak Hemi production ended in 1971, the 440 and 383 engines continued to provide thrilling performance.
Final Production Year (1975) • 1975
The last Road Runner models were built on the M-body platform, marking the conclusion of the iconic B-body era. Despite this, the Road Runner nameplate persisted in subsequent models, albeit with diminished muscle appeal.
Known issues by generation
When it comes to the Plymouth Road Runner and Superbird, understanding potential issues is vital. The 426 Hemi, known for its power, has rare cylinder-head-crack concerns along with common valve-guide wear and timing-chain issues in high-mileage vehicles. The 440 Six-Barrel's carburetor can present cold start challenges, while both the 440 Magnum and 383 Super-Commando engines often need carburetor rebuilds. Additionally, the Chrysler 727 TorqueFlite automatic transmission is robust but may experience valve-body wear, necessitating a rebuild. Rust issues also plague Mopar B-bodies, particularly in salt-belt states like Missouri, where unibody construction makes thorough rust mitigation essential.
Donation value by condition + generation
The collector car market for the Plymouth Road Runner and Superbird is robust, particularly for vehicles boasting numbers-matching engines, transmissions, and rear-ends. Original paint in high-impact colors is especially valued, with factory color changes viewed unfavorably. A premium is placed on halo trims like the 426 Hemi and 440 Six-Barrel, and documentation from specialists like Galen Govier is critical for authentication. Restoration receipts and provenance documents significantly enhance a vehicle's standing in auctions, with sales at Mecum and Barrett-Jackson confirming collector interest in pristine examples, often fetching prices beyond $300k.
Donation process for this model
Donating your classic Plymouth Road Runner or Superbird is a meaningful way to preserve automotive history. We recommend consulting a qualified appraiser experienced in classic muscle cars to assess your vehicle’s value accurately. Given the importance of documentation, including original cowl tags, fender tags, and broadcast sheets, it’s vital to gather these records for IRS Form 8283 Section B, especially for high-value examples exceeding $50k. Transporting vehicles in excellent condition via enclosed transport is advisable to maintain value.
Missouri regional notes
