8. 1971 AMC AMX
For 1971, AMC fully redesigned its pony/muscle lineup, combining the Javelin and AMX into one model. Gone was the two-seater version. Now, the AMX was the top of the line package for their Javelin model. As you probably know, if you wanted to run with the big boys in the early ’70s, you needed a big engine.
So for the Javelin AMX, AMC provided its biggest motor, the 401 V8. This mighty powerplant produced 335 HP which was a respectable number. However, the sales started to decline, although the 1971 Javelin AMX was one of the prettiest cars on the road in those days.
