I saw a Coronet Super Bee 68/69/70 I don't remember, I'd have to find the pix, at Mecum in Kissimmee last year. It had the Hellcat motor, brake upgrades, etc. Very cool car.
As far as "hybrids" go, I would certainly consider one, but NOT for my REAL V code 70 Roadrunner. To me, the legendary performance of the 440+6 A12 and V-Code cars means they MUST have a 440+6 under the hood...MUST! My 70 V-Code Roadrunner has a 71 440 in it, and I am in the process of moving forward with a stroker build for my car. It has the Edelbrock 6bbl aluminum intake and Holley carbs, and the stroker will as well. I am adamant about the 6bbl staying in place, knowing that more power and possibly more reliability, less tuning, and less "finicky" ease of ownership would be available via a procharger, turbo, or even supercharger. If I want more power than my stroker provides, my best option due to the MUST of the 6bbl being what tops off my motor is nitrous oxide-and that's it. It's a matter of what is important to the OWNER, and keeping the 6bbl and making the most of that setup is what is important to ME. Fortunately that isn't too bad of a "sacrifice" because the 6bbl has tremendous potential and performs very very well, especially in the light of modern alternatives.
The only exception I would make would be 3x2bbl throttle bodies as part of a fuel injection system, and those setups are made to accommodate the stock 6bbl air filter system...I'd be OK with that.
