I drag rac a 77 Nova that runs 6.78 in the 1/8 mile. Every week at the track they bring in station wagons. Moma had a 400 ci 4v 71 ranch wagon that would just blister the tires, I drove it as a kid. I always wondered why build a wagon? I figure a lot of them came from the factory with posi traction. Maybe it's a weight transfer thing....I dunno.. I thought lighter was better.
