Vehicle Details
“How much horsepower did the 1973 Road Runner have?”
The 1973 Plymouth Road Runner came with several engine options, each with different horsepower ratings:
• Standard 318 2-barrel: 170 hp
• Optional 340 4-barrel: 240 hp
• Optional 400 4-barrel: 260 hp
• Top-option 440 High Performance 4-barrel (GTX package): 280 hp
The 440 engine you’re asking about produced 280 horsepower at 4,800 RPM. This was the highest output available for the Road Runner that year, though it came as part of the GTX package.
Interestingly, the specific 1973 Road Runner you’re looking at has been modified and isn’t numbers-matching, so while it started life as a 440 car, the current engine may have been rebuilt or modified from the original factory specifications.
