Does anyone have production numbers on how many 1972 ModelJ had a 455 installed?

I don't have any specific data on that, but there were 13,560 455 engines in GP. (no designation of which ones)
There were 9398 SJ GP's made. So, if one figures all the SJ's were 455's (no clue if so), subtract that from the 13,560 total 455 GP. So more or less around 4100 'J' model GP?  Haven't seen any Fred Simmonds info on the GP.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
