If the rules were in place to minimize the possible changes then I don't see why it couldn't work. It all depends on what they allow as in off sets, engine placement, ride height, steering gear, fuel tank, etc. They could require a restrictor plate for the modern pavement only cars the first year or two so they could run at first. I think the rules would be pretty easy to enforce. Most of it you can tell just by looking at it. If it looks close, then measure. They should do this for sprints and midgets too. I miss some of those races. Winchester was one of the coolest places on the USAC schedule. BTW I fielded a dirt Midget that ran on pavement and a pavement Silver Crown we ran on dirt to an 11th place finish at Eldora with right hand steer and 4 link rear. It CAN be done!!!
