yeah, but it's a smaller bore/stroke (MUCH smaller than a BBC) so the effect will be much smaller due to a much smaller surface ares, and the testing was already done using motorcraft semi-synth. it won't be that dramatic.

Woe to him who builds his palace by unrighteousness,his upper rooms by injustice,making his countrymen work for nothing...Does it make you a king to have more and more cedar?Did not your father have food and drink?He did what was right and just,so all went well with him. He defended the cause of the poor and needy,and so all went well...But your eyes and your heart are set only on dishonest gain,on shedding innocent blood and on oppression and extortion.
