Long Block = whole engine including heads last I knew. Does long block man something else in the world of boxter engines? If the long block part number is the same, then that would stand to reason they are the same engine at least from a rules perspective.
I'm hoping to get a printout of both parts "pages" out of the parts list with the long block part numbers.
has anybody seen any discussion on this on Nasioc, or SCCA Forums?
