[442w30]

The GM Heritage Center has a lot of unpublished info on Pontiacs, but unfortunately no info on 1966 Pontiacs like this - a shame.

However, I have seen their 1967 numbers (which are for the 421's replacement, the 428) and it's interesting to note that the top engines were more popular on the Bonneville than the Catalina, 2+2 excepted. Prob is analogous to the number of L-36 427 Caprices you see versus basic Impalas, Bel Airs, and Biscaynes (at least from my observation).

I don't know if I have digital pics of the silver HO Bonnie I've seen as I'm overseas at the moment, but it has been to the Pure Stock races a few times over the years - prob been 10 years since I've seen it.
