What size engine for the online/Youtube EC?

Ok sharing a PDF link took me awhile to figure out but this should work. These are some very basic rules that are open to discussion. If there is interest we can take it to the next step. Tell me what you think--lets discuss. J.Rob

OEBC Rules
One comment on proposed rules, EQ heads are even allowed as factory replacement heads in dirt track circles running 500cfm carbs.

If speedmaster and eddy heads are allowed, then why not EQ and RHS heads?
