Spaw, I didn't think Lotus actually cheated. Being from sports and F1 racing, they see technological advancement as desirable. They went against what was basically developed-but-outdated (well, to Lotus, anyway)technology from the viewpoint of the then-latest F1 design thinking. Took the good ol' boys a while to catch up.
Another story now. Doubt if anyone will ever do that again.

My father worked in the Coventry Climax racing shop at the time their engines were the go for F1.
