Boy, I would. In my OPINION there are only two reasons to put up with all of the headaches that come with owning one of these old cars.
1. The nostalgia look of them.
2. The TORQUE that a big block provides. For me, the more torque the better.
The new Mustangs and Challengers and soon to be Camaro are basically in the same league as many of the performance cars of the late 60s and early 70s. They are rear wheel drive cars that we can buy new for the price of the typical family sedan, with warranty, better gas mileage, easy to insure, run the same 1/4 mile times, run higher top end speeds, and can be driven as a daily driver as well as take to the strip on the weekend. Sound familier? Say like a 69 RR or Bee when they were new?
The old cars offer big blocks C.I.D. that you can't get today unless you want to spend MUCH more money for something like a Viper. This is why all of my old cars are big blocks.
I have often thought about selling all of my old iron and buying a new car to replace them for these very reasons. In fact, the days are not far off when I put my 1966 Hemi Coronet up for sale and replace it with a 97-2001 Viper. My 66 has never had a roll bar in it and when I am barred from all the area tracks for running too fast without one I will sell it as iIdon't have the heart to put a bar in it after 43 years.
