Off Kilter Racing is running a 62 Valiant 225 slant six. And Escape Velocity Racing is running a 64 or 65 Dart 225 slant six with a turbo. I think there is also at least one other turbo slant running. Here is a thread about an up coming race. (2) Lemons at Carolina Motorsports Park - April 23-24, 2022 - Slant Six Forum
