Have spent some quality time on the site reading about these flat head engines. Tried to search for the differences between the 8ba (or is it b8a?) and the 59ab. As described earlier, this car has a Merc engine (where it is to have the 4" stroke) also has the thin water pump pulley configuration.
Just really enjoy getting to know more about the engine and all the mods that can be done to these tried and true machines.
Thanks for your help in advance.
Test.
