the Performance Research Racing (PRR) team entered this Challenger in the 1970 Trans-Am SCCA






The dealership sold new Challenger needed approximately 1,500 hours to become race-ready. 

Notably, the factory dashboard, interior door panels, and quarter panels remained untouched. Due to regulations prohibiting the modification of the car’s body to accommodate larger tires, the rear quarter panels were instead flared to provide additional clearance for the tires. Finally, clips and straps were added to secure the front and rear windows.

Sheet metal was welded between the back seat area and the trunk. The battery was relocated to the trunk. A chin spoiler, crafted from aluminum, was bolted on to assist with front downforce. For the rear spoiler, a Camaro spoiler was used due to the unavailability of a Mopar spoiler in time.

Initially, only corporate race teams received funding due to company politics, but by the end of 1970, even this support ceased. Independent teams like Performance Research Racing lacking factory sponsorship, couldn’t afford an engine. Consequently, their car was sold without one.

The new proprietors procured a Keith Black engine to complete the car and prepare it for racing. Feeding through a single Holley 730 cfm carburetor, the racing engine would produce around 450 hp.

Behind the engine, an A-833 4-speed manual with NASCAR gearing replaced the 727 3 spd auto. The rear axle was a stock 8¾ with 3.55 gears.

The car resurfaced on October 3, 1971, to race at Riverside Raceway in California, once the green flag dropped, the Challenger ran 13 laps but succumbed to engine failure.

This de-stroked 340 cid engine proved to be unreliable for racing. Originally not designed for racing, the 305 cid suffered from oil starvation issues going through corners at speed. 
SCCA regulations prevented the use of dry-sump lubrication, which would have been an instant fix.

Raced for the 1974 season until engine let go, plus the car was ill-handling in the turns due to the fact that it was so nose-heavy. At this point, the new owner decided to move the firewall back to distribute the weight more evenly and help run on the oval track. He started on the project, but he just did not have time. The car was covered and put in the corner.

His son, in 2005, after looking at the car for 30 years, decided to restore it as it raced in Riverside back in 1971, the last attempt by an independent team.

You might have heard of the Challenger Pace Car catastrophe... but did you notice in the article about that crash, that John Glenn was in the car? I didn't, and I posted the dang article in 2017!



That year’s race didn’t have a factory-special pace car but a 71 Dodge Challenger that a local dealer provided.

Sitting next to Palmer was IMS owner Tony Hulman Jr. In the back seat were astronaut John Glenn, the future U.S. senator from Ohio, and ABC sportscaster Chris Schenkel. They plowed into the camera stand at an estimated 60 mph.

 After the opening lap, the car pulled into the pits, missed the braking point marker, failed to stop correctly, and took down a photographer’s stand, injuring 29 people. 

John Glenn, national hero 

 Prior to this spectacular crash, he had cheated death several times before, while making history. 

He was a test pilot for the Marine Corps, made the last air kills of the Korean War in July 1953, and crossed America from coast to coast in 1957 in a supersonic flight, and orbited the Earth three times in 1962.

the first 3 cars I owned, all rusty and mostly painted rattle can gray. 1992-94




 72 318 Barracuda I made a 340, 71 Challenger 340 and 727, 72 Demon 340 and 904. 

I think I paid 400 for the Barracuda, 1200 for the Demon, and 3k for the Challenger. I loved those slotted mags. I got the back ones from a guy who bought them for his 68 Road Runner, and they won't fit on that 68 Road Runner unless you change something about the back and he wanted to keep his car stock except for the wheels.

on the road to Summer Jam, 1973, Watkins Glen

 looks like that Mustang is missing a back panel, under the bumper, or is it simply jacked sky high? Bald tires?
