Another issue is the advance curve of the 11A. Although very good for the stock engine, it comes snort for the cruise toming with present day gas. This can be addresed by opening up the advance slots, but the stock springs pose a problem. As Bruce pointed out, it's more esthetic than necessary. Someone is making a distributor modification to the 11A for dual head spark plugs (16 wires)$$$$$$$
