Kind of hard to debate that one...they started eviscerating musclecars as early as '68, although the 340 didn't get seriously hacked until '72 when they dropped the compression to 8.5:1 and intake valve size to 1.88......The TQ was installed on the '71 Duster and did very well on that car. Actually, the '70 Duster with the AVS was quite respectable as well.
