Here are the excerpts from the "Standard Catalog of Pontiac 1926-1995":
What's strange is that they don't list any production numbers for the Tempest 23337, but they do list 20,883 produced as T-37 23337s.
According to the production figures supplied by PHS, 20,883 accounts for ALL the 23337s in '70, but they don't seem to distinguish Tempest from T-37. The PHS sheet states "Tempest (T-37 in '71).
There's an example of a VOE GTO built many months after the program had been killed off, and there's a theory that Pontiac may have an honored an order that had been placed prior to the option being killed. Had the car been ordered prior to the T-37 announcement but built later, maybe it was built as a Tempest.
Since it wasn't an option package (like the GT-37) and merely a marketing name, there may be no scientific way to determine if a '70 hardtop is a Tempest or a T-37 unless there are early photographs of the car.
