Clean, green muscle machine: 1970 Plymouth Roadrunner coupe


 If the rumble of classic American muscle does it for you, the Pick of the Day should hit the spot: a 1970 Plymouth Roadrunner with a massive 440cid big block V8 under its hood.  As an added incentive, it’s the only muscle car named after a Warner Brothers cartoon character. Beep-beep!

The Limelight Green coupe has been completely restored, according to the private seller advertising the Plymouth on ClassicCars.com. While the 440 Six Pack is a replacement crate engine, the Roadrunner looks, sounds and performs as original, the seller says. 

The restoration was a “complete rebuild, top of line, no short cuts, done right,” the seller says in the ad.   The 4-speed manual transmission also was rebuilt, the seller adds. 

The big-block coupe would be a hit at the local car show

The Roadrunner has had a few upgrades for added comfort and drivability, the seller says, including better stopping power with a set of Wilwood disc brakes up front – “Stops like a new car!” – Vintage Air air conditioning and a modern audio system, but with a retro look.

This 440 coupe cuts to the heart of the muscle-car era, a flamboyant look with the torque to back it up.   Model year 1970 is considered the apex for high-performance muscle from Detroit, before the feds and insurance companies put the brakes on the horsepower wars.

The 440 engine equipped with the tri-carb Six Pack was officially rated at 390 horsepower and 490 pound-feet of torque, although contemporary testers believed it actually produced much more.  Full throttle was described as “explosive.”

The interior looks to be in as-new condition

While a Roadrunner coupe equipped with the famous 426 Hemi is more valuable as a collector car, there are no excuses necessary for this build.  The seller notes that the engine has been modified with a roller-bearing camshaft and Thunder exhaust system that “sounds awesome.”

The car looks exceptionally clean in the photos with the ad, with detail shots of the underside that look like new.  The Limelight paint other trim details are as original, the seller says, other than a set of period-style mag wheels.  The car has 78,000 miles showing. 

The asking price for this attractive piece of muscle mayhem is $59,900, or best offer.
