Re: Most Under-Performing Musclecar Ever Produced?
Paul is correct on the year M/P began. All of the limited production FX cars from 1963 that had alum. front ends were put into Modified production in 1964 and had to run 7 inch cheater slicks. I remember Malcom Durhams 63 Z-11 Impala setting the A/MP record at some point. The 63 421 SD Tempests (coupes and wagons) ran A/MP also.
