Hey everyone!!
I was looking for some reference photos as well and this thread keeps popping up so I thought I would chime in, start some more discussion, and hopefully help somebody else looking for reference photos. Somebody referenced the hot rod magazine article from 1972 and here is the link to that article.

As we can see from the engine picture, it's quite a bit different from the very famous picture of Jenkins standing at the front of the car and his crewmembers standing at the driver side. That picture has the hood off with an orange engine, dominator carburetors, and the fender well headers. It's almost like that picture is either a very early picture, or they just threw an engine together for the photo.
The picture from the hot rod magazine article looks like it's a black engine, black cylinder, heads, aluminum valve cover extensions to clear roller rockers and factory style valve covers. The article also states that he tried dominators at some point, but they weren't worth the hassle or the minimal horsepower gains.
Of course this was December 1972, 10 months after the car made it original debut. I'm sure they were changing stuff the entire entire season.
