I think that's the Lotus 2.2 (or maybe only 2L) slant 4, not the xflow based with Twin Cam head.
That engine was in the Esprit (with a turbo) and was also in the Sunbeam Lotus hatch as well. It was in the Elite as well. From wiki
"The Elite was Lotus' first car to use the 907 aluminium-block 4-valve, DOHC, four-cylinder, 1973cc, developing 155 bhp. (The 907 engine had previously been used in Jensen-Healeys.)"
I have seen a pic from a show in the UK with that engine in a Mk1 Escort though. I might have a pic of that somewhere.
