Initially I misread that as a Ford Cosworth engine! Should have gone to Specsavers I suppose.
That would be a whole bunch of fun. I've wondered if it would be possible to squeeze a BDA into my 4/4 - not that I could afford one!
I posted a picture of just such a beast a few years ago which if I remember correctly was one of John Shealley’s race cars over in the States.
It looked pretty special. https://www.classyvice.com/morgan-cosworth-bda-for-sale/https: Not the only one around it seems.
