I know the owner of 1 of the M22 cars. Almost every option on that car...

Paul never said that you could not get an M20 (or an M22, or an M13) with the L72 engine. He said (correctly) that you could not get an M21 (in a full size car) behind any engine except the L72.

The "literature" he posted says the exact same thing. Go back and look at it again. It shows "4-Speed Close-Ratio" and "4-Speed Wide-Range" and "Special 3-Speed Full-Synchro" as available transmissions behind the L72. (M22 was never listed in the showroom materials in 67 or earlier, hence why so few were built.)

The point is simple: 2Q means M21. M21's only came behind L72's (in a full size car in 66). Therefore, 2Q necessarily means the car came with an L72.

That does not mean (and no one ever said) that every L72 must have 2Q on its trim tag. An L72/M13 or an L72/M20 would not have 2Q. And even some M21 cars (depending on where built) were not coded 2Q.

But if 2Q IS on the tag, it was an L72.
