In 68 or 69, I would have ordered a 4 speed because I 100% knew real race cars had stick shift transmissions. Come 1976, when I was going faster with an automatic, using the same engine in a heavier car, I realized that between the breakage, the slower e.t.'s and inconstancy, a 4 speed wasn't really all it was bragged up to be. My big screw-up was turning down the name brand racing automatic and matching converter that one of my sponsers offered me in 1970. That was a real bone head move.
