1968 Plymouth Road Runner

Mike Brogniez · 09-20-2011, 07:11 PM

Had a dark green 68 sedan with the rear pop out window and a black vinyl roof and tan interior stick (hurst) car.
There was quite a bit of work done to the engine, tranny, gears, front end and cranking those torsion bars as required.....
It was a fun drag car, with slicks and narrow fronts on Keystone mags...it also won its fair share on the street with the red lines and small hub caps.
Still have some of those trophies.....somewhere.....
The guy I sold it to totalled it two weeks after he bought it............

Just pulled out an old 1968 Drag News,
found one of our friends winning in E/SA in August 1968.

Ran a 14.72 @ 95.50 MPH, in winning a Class Trophy at Dover Drag Strip.

A completely stock 383 engine and 727 automatic transmission, with Hooker Headers, 3.55 gears and 7' slicks,,,,,,,Oh,,, and 'foam dice'
hanging from the inside mirror.

Road Runner Fact;
The interesting thing about the 1968 383 Road Runners.
The 3.23 gears were standard.
The 3.55 gears could be ordered with the 'performance axle option' ($88)
The 3.91 gears could be 'special ordered', for an additional ($55), on top of the ($88) option.

4.10 gears from the factory were not available. Not because it was harmful to the cars
engine and drivetrain. It was because the Plymouth GTX sales and marketing department was afraid that a 383 Road Runner with 4.10 gears might outperform a 440 GTX with 3.55 gears.
And that, as we all know, would not have been too good for GTX sales.
