If I had the money, and I don't think I will in my lifetime but there's enough of an outside chance that I can dream about it...
I would do a Superbird clone, Lemon Twist and Black, with a Hellephant engine and a 5 or 6 speed manual transmission that could handle the power. The absolute best suspension system available and the same goes for brakes.
THAT my Mopar friends would truly be a SUPERCAR. I'm absolutely certain that the power output would exceed that of the Nascar Hemis, and with the suspension setup and the aerodynamics dialed in, along with the OD 5th and/or 6th gear, with enough geography it would be a top speed terror, AND still rip one hell of a 1/4 mile.
Yep, that would be a dream car for me.
Now don't get me wrong, I will be able to get "a taste" once I get the QA1 K-member and front suspension system I already own installed, the triangulated 4 link rear suspension I want to get asap, the 6 piston caliper on all 4 wheels Wilwood disc brakes system I have lined up, and the stroker motor I have planned. I already have the Passon a855 5 speed, and I love the way the 5 speed plays with the 4.10 ring and pinion gearset in my Dana 60...
But still, bigger dreams...
