T/A for me ALL THE WAY! Best looking Challenger IMO and way fewer real 340+6 cars than 440+6 cars. The side exhaust, spoiler, fiberglass hood scoop, and T/A stripe (all factory) really make the car look special too.
FYI:
1970 T/A's 1,411 Auto / 989 4 Speeds = 2,400
1970 AAR's 1,604 Auto / 1,120 4 Speed = 2,724
1970 V codes (hardtops only)
Challengers = 1,936 (R/T & R/T -SE)
Cuda = 1,755
Unlike T/A's and AAR's, the 440+6 was put in B-Bodies so there's another 4,491 1970 B-Body 440 Six packs. Bringing the total of 1970 440+6 to around 8,182 (plus few hundred convertibles). AND they made 440 six packs in 1969 and 1971 too. The 340+6 T/A and AAR is one year only 1970 and there are about half has many of them as there are 440+6.
Thought they built 2500 T/As?
