When it comes to racing, everything is important. Power/weight, gearing, traction, power band, etc.
This is not to even mention driver skill. You could switch drivers in a lot of races and the opposite car would win. Then car prep/tuning. I remember a thread I started a while back about Grumpy Jenkins and someone told a story about a friend owning a ‘62 fuely Corvette that originally belonged to Grumpy and it was scary fast.
Not trying to take anything away from the Mopars but sometimes there is more to the story.
