Mopar Mayhem – 1970 Plymouth Road Runner vs. 1970 Dodge Challenger

September 25th, 2021

We have another old school drag racing video for all you gearheads. This time, it’s a pair of the most iconic Mopar muscle cars ever produced. Both these cars have been pristinely restored to stock condition. Today we see which one is fastest in the quarter-mile.

In the right lane we have the 1970 Plymouth Road Runner. This cream-colored Road Runner (black vinyl top) is powered by a 426 cubic-inch HEMI engine with a dual four-barrel carb setup. This arrangement is rated at a conservative 425hp. It has an automatic transmission and a 4.30:1 Sure Grip rear end. This stunning Plymouth is 1/287 produced.

Pounding pavement in the left lane is the 1970 Dodge Challenger R/T in purple. Under the hood is a 440 cubic-inch engine with a triple two-barrel carburetor configuration. Maximum output for the Challenger is estimated to be 390hp. The final drive gear ratio is 4.10:1 and the transmission is an automatic. This purple pavement-eater is 1 of 2,035 produced.

Careful guys! These cars have a resale value estimated at forty-times their original sticker price of $4K.
