Car Guese

The Boss 302 was rated at 290 HP because insurance companies were beginning to penalize the muscle cars by tacking on higher charges to any car rated over 300 HP. Actual horsepower was closer to 350. (These are Gross HP figures, not Net, as used today). Race versions made 450 HP at over 8,000 RPM

Perhaps the 1969 Mustangs greatest aspect is that it managed to be new and exciting visually while still being instantly recognizable as a Mustang. Automotive critics of the time called it "more adult" and "more serious" than the Mustangs referred to as the "late 65s". Even today, it's tough to argue with that assessment. The 1969 is a mean machine, and it looks it. This is a bullet ready to smoke that car you're driving right off the line.
