Designed and built by Gordon Allen from half a 1700cc BDA (so rated at 850cc). In the 1970's special saloons there was an 850cc class which was full of destroked/overbored 970 Cooper S engines, usually running exotic 8-port heads and the like. This 2 cylinder BDA was a real winner once a few niggles were overcome. It was used by Peter Day in a Mini and also a Fiat 500 (the "Mighty Mouse") Here it is at home in the Mini;
