Ex-Tasca 1970 Ford Mustang Boss 429 Drag Car With Richard Petty NASCAR Engine Now Up For Sale

A rare 1970 Mustang Boss 429 drag car with Petty Enterprises racing heritage

Few classic Mustangs have a motorsport history as compelling as this 1970 Ford Mustang Boss 429 drag car. Originally delivered to Tasca Ford in East Providence, Rhode Island, this example combines one of Ford’s most celebrated homologation engines with a fascinating connection to NASCAR legend Richard Petty. Now offered on Bring a Trailer, the extensively documented machine represents a distinctive chapter in the Boss 429’s racing legacy.

Identified by Kar Kraft serial number 2124, the Mustang was originally finished in Grabber Blue and modified for drag racing by Carl Tasca. Its most significant feature is a NASCAR-specification 429ci Boss V8 sourced from Petty Enterprises. The engine had reportedly been used by Richard Petty during the 1969 racing season, when he competed with a Ford Torino Talladega.

Rather than retaining the standard Boss 429 induction arrangement, Tasca fitted the engine with a Weiand tunnel-ram intake manifold and dual Holley four-barrel carburetors. Custom four-into-one headers completed the installation, while a domed, lift-off hood provided the necessary clearance.

The engine features a cast-iron block, aluminum cylinder heads, and magnesium valve covers. It was subsequently rebuilt under current ownership by George’s Speed Shop in Dayton, Ohio, with International Drag Racing Hall of Fame inductee Ohio George Montgomery overseeing the work.

A Documented Drag Racing History

The Mustang accumulated approximately 3,000 miles by 1974 before being sold to Connecticut drag racer Henry Austin, who continued campaigning it throughout the 1970s. Historical sales documentation dated September 30, 1974, identifies the vehicle as a race-purpose-only machine and records a $4,500 cash transaction.

The current owner acquired the car in 2014 and commissioned a refurbishment at Delisio’s Performance in Lyons, New York. Completed in 2015, the work included refinishing the body in its original Grabber Blue. The exterior retains its white tail panel and contrasting hockey-stick stripes, alongside rear window louvers, exposed hood latches, and a chin spoiler.

Mechanical upgrades include rear chassis reinforcements, traction bars, American Racing 15-inch magnesium wheels, and Goodyear Polyglas GT tires. Power reaches the rear wheels through a four-speed manual transmission, while braking is handled by front discs and rear drums.

Inside, the Mustang retains its white Corinthian vinyl upholstery, high-back bucket seats, woodgrain dashboard trim, and factory-style instrumentation. The five-digit odometer displays 3,300 miles.

A Rare Piece of Ford Racing History

Offered from Maryland with historical photographs, documentation, service records, a build sheet, and a Deluxe Marti Report copy, this Boss 429 has considerable historical appeal.

The car is currently bidding at $150,500, with the auction scheduled to conclude November 17, 2026. It is sold on a bill of sale without a title or registration and is not road-legal, reflecting its dedicated competition history.

For collectors, its connection to Tasca Ford, Petty Enterprises, and Ohio George Montgomery makes this considerably more than another restored Boss 429. It is a surviving example of the era when factory muscle cars became formidable weapons on American drag strips.
