Technically speaking, there is no such thing as functional and non functional. Not really sure where or why that term has been coined and repeated.Wasnt Functional and Non Functional hoods an option only on SS's? Malibus got flat, Heavys got Non Functional correct
the standard SS (domed) hood was on all SS cars unless RPO ZL2 (special ducted hood) was ordered.
All non SS cars received the standard flat hood. I can’t speak for the 71-72 heavy Chevy cars since I never really researched them.
