To me when looking at engine options from the day. I see perfomance mods to make more power and increase performance. Ram Air terms in regards to pontiac was just there little niche. I believe later in production the did make cars ram air IE; 70-73 formulas. But we have talked that the functional scoops on early birds done very little for performance. Any head modification improves performance. Basically they put racing mods on stock cars from the day and did a word play to inhance sells.
