Low-to-No-Options / Unusual Option(s) ...

67 Dart, 2dr 170 slant six, only option was a 904 auto. no radio, and heater delete. Friend of mine bought it last year to build as a drag car (pretty rough shape).

Also my 65 Valiant 100 2dr post. 170 slant six, 904, heater. no radio. Bought in 1975, from original owner.

They were still using the 170 slant in 65 and 67? Or did you just use that motor to beef them up?
