i would step over my own mother for a blown 571 big block with duel king demon carbs. Fuel injection is nice. But i am partial to carburation for a musclecar.
I would also like to see the hideaway headlights, although it's not going to happen. A full hotchkis suspension setup. Sport and cruise mode that lowers the car closer to the road for a true G-machine.
I would also like the vette exhaust tips molded into the body for a side exhaust behind or in front of the rear tires. More hood choices with a retro look.
pushbutton start with electric and fuel cutoff switches.
So i am basically describing my Camaro in my garage right now but some of these things would be nice in the new Camaro.
