This is a non-VW specific question. I have the car classification worksheet: http://www.scca-milwaukee.org/...n.pdf which states that ‘engine swaps other than direct replacement’ are classed in Street Prepared, otherwise known as section 15 of the SCCA rulebook. However I cannot find ANYTHING in section 15 that allows any kind of engine swap. Intakes, Throttle bodies, valve jobs, headers, are allowed but no engine swaps. Engine swaps seem to be covered under Street Modified rules. Am I correct in this? Otherwise, what does this worksheet refer to as a legal swap?
