From Greenman:
Keeping in mind how Can Am worked historically it was a sports racer out growth of the USSRC racing series. Early cars were tube-framed, which later gave way to monocoque racers. The rules were basically "no rules" whatever you could do to go faster was okay... later it was a bit more structured. This included cars with moving wings (chaparral) vacuum traction assist (chaparral again), moving bodies, multiple engines in short... whatever. What really killed the series was the money chase and timing. On one hand, Porsche just out spent everyone else and ran the little guys out of the series. Add to that, the early 70s oil shock and didn't help either. Ironically the last Can Am Championship was won by the UOP Shadow a titanium monocoque car driven by George Follmer.
Might I suggest two classes? Early cars with an under 20k motor, configuration gearing, etc open. For to reflect the tube frame cars. And a later car series with a 25k motor limit and one (gag) magnet? This would represent the later cars that showed the progress learning about aerodynamics really worked that took place over the years. Both series should allow alloy wheels and scratch building, thought I feel Slotit McLarens may dominate the late cars as the Slotit Chaparral may dominate the early cars. How do you guy feel about it?
