Thanks for reply Dave. There is plenty of discussion on the Mustang forums on this issue with BBK offering 85mm upgrades for the Coyote V8 engines and the old 80mm bodies being re-drilled to upgrade 3.7 V6 versions.
Worth remembering the Cyclone V6 was used in a wide variety of other vehicles including Lincoln's, F150 trucks and, dare I suggest, Transit vans
. This then begs the question which model engine variant the composite inlet manifold was borrowed from (certainly not Mustang) and, given little interest from Ford, how MMC ended with their logo moulded into same
