Classic Cougar Drive Trains: 1970

Cleveland 351 2V

1970 Engines:

Once again Cougar got itself a new standard engine--the 351C 2V. On paper, it looked nearly identical to the 1969 351 2V Windsor, but in reality, it was a completely new engine with a significantly different design.

For performance, '70 Cougars could be had with a 351C 4V, a Boss 302 or the big CJ 428. According to some sources the Mustang Boss 429 was also "officially" available, but the best records available indicate that only two '70 Cougars were so equipped.
