I guess EJ Potters Chevy and the Drag Waye VW would be the most famous car engined bikes,but there were quite a few in the 70s.The Imp engine seemed a popular choice,all alloy ohc 4 cylinder and the scrapyards must have been full of them.Here's a few starting with Moonraker from 66 which featured an English built flat 4 AJB engine.
