Sadly, this is the only picture we have of it. Everything else is just built off what he said.
Both kits came with a 265, and had different air filters on top, but other than that they were the exact same. And, the only 327's I could even find (other than the actual kit of a 327, like 1/6th scale) was either the Nova SS you mentioned, or the 64 Impala lowrider, which I have neither of. Oh well, the one that came with the street machine looks good for it.
Oddly enough both kits were exact same with the exception of the exhaust, wheels, and side peices for the bed. I was expecting a bigger more "tuned" engine or somthing for the "street machine" version, but its not. Tree for tree other than one small section of the engine tree and some of the chrome tree, they're the exact same, only one is white and the other is a purple color. Plus for some reason the hood fits better on the "street machine" version..
