I will agree that they don't ride as well as today's tires, BUT, they CAN get better traction! Need proof? Just look at the Pure Stock Muscle Car Drags, and see what tires the front runners are wearing...that's right, repros! The key, explained to me by Dan Jensen, is to "pump 'em up", to around 40-45 lbs. or so. It all depends on the footprint you leave, which can be checked by leaving a short black mark. You want the mark as wide and as evenly dark all the way across as possible. A little experimenting with air pressure is all it takes, and you will definately notice a difference between a pumped up tire, and one with lower air pressure. Don't leave the high air pressure in them all the time, as it will stretch the tire.
There was an article in Muscle Car Review
a year or so ago explaining this very thing, and it should be read by anyone who takes driving there muscle car seriously. They compared a set of repro Polyglass tires to a set of newer radials, and the Polyglass kicked BUTT! They said it was due to there being little space between the tread of the Polyglass, which led to little or no tread shift, which means it is kind of like a skinny slick. The smaller the grooves, the more rubber on the road. The big drawback here, though, is wet weather driving, which is kind of hairy, especially for us big block owners! I would definitely recommend the repro tires.
