Any idea what these letters mean? They are on the firewall of a 1970 427 4 speed Nova.

I think they mean its not the original engine. j/k

where exactly on the firewall are these marks?

I know its not the original engine. If you are looking at the firewall from the core support they are on the passenger side behind the valve cover down towards the bottom.

Could it possibly be salvage yard markings from a car racked....maybe even w/ subframe removed so you can read it from below? . What's it say...G 1 G B B? . BB for Big block? . Pretty aggresive markings for a line worker? ~ Pete

Most of the 70 Novas I've seen have some type of marking - under the black paint. The codes are usually duplicates of what is on the trim tag, usually written in white grease pencil, and were for the line workers to know what to install, etc..

Big yellow stuff like that refers to a body color change done by Motion, although usually found in the door jam - so you must have a Motion Nova
