BMFC, Tiiming, and Coatings

[Steve]

It is a very common thing to do on a race engine that is rebuilt on a
regular basis that is cast iron.  When I worked at Electramotive all of the
cast iron engines were painted to speed up the clean up time during rebuilds
and to prevent casting sand from being shaken out of the knooks and
crannies.  Yes you can grind out and polish the inside, which we did to the
major nasties, but we still painted it.
