Geoffs car had a prototype 4 bolt motor in it when it was 'destroyed'. The report we have was presented at the meeting that gave the green light and by then they knew they needed platforms to test the first MM engines. Since there were no 89s at that time the 88s were used with initial production MM engines. If you look at my engine s/n 42 it was installed in June of 87 (We know this because I have an engine build book that was in the crate) in P8Y078 EX5005. This engine then appears to have been driven 4486 miles then is back at Lotus in OCT NOV for 36.67 hours of dyno time. It was then stripped and the block ended up in the graveyard where Geoff rescued it and built my motor.

Makes sense, but I would still like to know what "Not CAT" means. When the comment says "1st MM Engine" I wonder what that means. 1st Phase III? I assume the Phase II that yours has came from MM?
