Here's an interesting quote from Mike again:

"In circle track racing, there are a bunch of classes, where the engine rules are almost identical, but some are limited to lower compression.
These classes run the same size engines, heads, manifold, Carb, and turn the same RPM. The lower the compression the tighter the LSA and ICL needs to be."

Wonder why lower compressions ratios like tighter LSA's......
