how to know if my 1968 273 motor is a super commando and also can you put 340 heads on a 273 block
As i remember you have to notch the block for the big valve. Special head gasket is also required. I have a 273S ( pan to intake ), if you're interested.how to know if my 1968 273 motor is a super commando and also can you put 340 heads on a 273 block
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.weren't super commandos 383's or 440's only ?
