Sounds like Va sux on their antique vehicle laws. In WV there's 2 different types of antique tags, you may wanna check and see if Va offers 2 different ones.
First kind here, you can drive it any day of the week but you MUST get an inspection sticker yearly. I guess this would keep a lot of vehicles stock.
Second kind you dont need to get inspected but you're restricted to driving only on the weekends (12PM friday through 12pm monday), or to club events, car shows, or to do "maintenance" such as driving to a garage for exhaust work, or even to go put gas in it. It still needs to be insured but other than that you're wide open on rules. Some of the local guys lift their truck high as they can, run biggest tires they want with no fender flares, and run open headers, and get away with it! I haven't been brave enough to try running around on open headers, I figured a city cop would still pull me over for a local noise ordinance or something. Good luck Dave, being in Va though I figure it's going to be pretty strict. Your truck would probably do best with 2-1/4" to 2-1/2" exhaust, duals of course with an H pipe, and maybe a pair of fromaster 40s. Just try to make sure the exhaust guy doesn't do any 90 degree bends, 135 degree at best (45 degrees if you're looking at the wrong side of the protractor lol), which is why many people exit them in front of the back wheels.
