The Ford CVH engine may not be much in favour nowadays and the standard Mini gearbox was always an issue with these period hybrid engine conversions (Ford Crossflow/BDA/Lotus Twin-cam, Imp, etc)....however I think the engineering innovation necessary to create them and make them work is more interesting than the more modern method of dropping in a modern transverse fwd engine/gearbox complete from a Honda/Vauxhall/Rover/Suzuki/Nissan/other. Back in the day there were few compact alternative fwd engine/gearbox units available for swaps other than the Austin Maxi or BMC 1800 which were really too heavy and bulky to offer much of a power advantage and usually compromised the Minis handling.
Dare say made complete sense at he time......especially as put together by Steve Harris - its a bit of an ugly engine though in my eyes...!
I think, the BDA conversions always look good and "period"
My Scout master (yes I was Scout for a couple on months..) had a 1600 Lancia engine and gearbox in a Mini, which despite having the front lengthened a bit looked really good, apparently, though, the front started lifting over 105 MPH !
