Marco, right you are. The "Fairlane" series engine has the same derivation of cylinder block as the 255 4 cam indy engine. The ndy motor was never designed to be a torque beast, but rather to generate maximumhorsepower in a very narrow rpm band. It was never a "good fit", application wise for the '40. It did have a strong aluminum block with pressed in cylinder liners; one that allegedly was used together with the Gurney heads on many GT40s. Remember at that time Ford had no other aluminum block in production; it was the iron age in Dearborn.
