'66 Barracuda 273 Commando VS '71 Charger 383

I would not trade. I never liked those 71s.
The cubic inch to weight ratio is close to the same for either.But it would take over 500 cubic inches in the bigB to equal a 360 in the A.
I could see how you might want to tho, seeing all the work that the Barracuda needs.
