273 motor

weren't super commandos 383's or 440's only ?
Yes, I believe so but in name only. They were de-tuned 440's in 72,3,and 4. Dodge had the MAgnum and Plymouth had the super Commando in their 440. No "Super Commando's" for HP 273's for Plymouth. 65,66,and 67 were the only years for the 4 barrel 273.
