Cheaper engine that can kick ass on the SOHC for hours on end. A world beater that is so vicious that the FIM told them to take the engine home and don't bring it back. An engine that won 3 straight Le Mans where the SOHC was SUPPPOSE to be superior but wasn't and Ford knew it.
Never said anything bad about the FE, only the stupidity of OHC heads on a engine that only added unreliability and nothing else.
