There have been several land speed cars with inlines in them, both straight 6 and straight 8's and even several Flathead Ford transplants in to RX-7's and other later sports car bodies. Since your close to the Ohio Mile races, it might open up the possibilities for you in that venue if you are interested in that type of thing. You would never be competitive with the later 250's or 292's, but with the earlier Stovebolt's, GMC's or even Straight 8 Buicks or Flathead Ford for the vintage classes you could have a better chance with the sleek body lines and aerodynamics of the RX-7 to set a record or two.
