I had a box of chrome bits in my garage, and I decided to clean them up, and when I got to the bottom, I found (and still have) a newspaper clipping from when I lived in Houston for a 1971 CUDA, 426 HEMI, balanced and blueprinted, dominators, tunnel rams documented $8300 parts. Quit racing, car & trailer, everything $5,000.00. I guess I bought my Buick GN because I didn't want to be working on something all the time. I don't remember. It doesn't say 4 speed, but it's enough to give me pistol grip envy, too. It's from around 1987 or so.
