I have aftermarket Model "B" engines in both of my Model "A's." Both engines are strong runners 5.5:1 heads.



I always iterate the ignition timing starting with #1 at TDC on compression. Typically, this results in timing that is excessively retarded, so I tweak the distributor's cam position until I get full advance without any audible knocking. Both cars will do 70+ MPH.
