Verne,

IMO...OP wanted to know how to properly detail a 1969 era 350/300 and there are multiple prospectives introduced in an attempt to assist and answer his question, they are:

Bright accent vs non bright accents.
SS with cowl induction equipment vs standard hood equipment
Tonawanda engine Mfg assembly detail vs Flint engine Mfg assembly detail.
Images supplied from both Camaro and Nova.

So yea it looks a bit confusing... the long and the short of it is that the engine was mostly painted orange the primary differences being the amount of over spray and assembly order differences between both engine manufacturing plants.
