There was a '62 Nova down the street from me when I was a teenager that was wicked quick. Still remember that car, had 4.56 gears and would launch pretty impressively I think your car would look great with chrome wheels and white walls. I owned a '55 210 2 dr sedan back in the day. I had chrome reverse with thin whitewalls in the back, and blackwalls with dogdish hubcaps on the front.
I'd run original full hubcaps with the whites you got on it right now. if I were inclined to get chrome wheels I'd run whiteys as well.
A car like your's in 67 would have had skinny Cragars on the front and rallys in the back with as much tire as you could stuff up in there. At least the street racers around here looked like that. As to the whitewalls or blackwalls, white was for cruisers and black was for racers. That being said, I think your's would look great with Chromies all around with the slicks in back. Nice car no matter what you decide.
Looks good like it is,back when I was in school best friend had one killer 327 4 speed chrome reversed in the front and blackwall black rim and black wall rear
