Why It Matters
The Pontiac 400 Ram Air III engine assembly covers the D-port Ram Air 400 path used by 1970 Firebird Formula 400 and Trans Am references. For Formula pages, it is tracked separately from the Trans Am-only Ram Air IV path so engine, carburetor, induction, transmission, and axle evidence can stay documentation-led.
