Sport Option
Short answer: “400 Sport Option” is a label seen in the parts and accessory catalogs. The “400” option included more than the engine — it added appearance and performance items: chrome grille moldings, the front-bumper Pontiac Crest emblem, “400” emblems on the hood and deck lid, redline tires, chrome engine trim, dual exhaust, the 4-barrel carb, and firmer shocks/springs.
In the accessory catalog, a “Sport Options” heading actually grouped all the Sprint, 350, 350 H.O., and 400 models — so effectively every Firebird except the base one-barrel OHC-6 was a “Sport Option.” In common use this got shortened to just the “400” option. It’s referenced in the 1968 Pontiac Sales Manual.
