Not sure about 74 but I know starting in 75 the 350 2bbl was standard in the formula with the 350 4bbl
and 400 4 bbl were the optional engines, I know the formulas in 75 had a "formula 350" or "formula 400" emblem on the fenders and only "pontiac" on the grills
I belive 76 was the same way as 75 unless you have the optional large formula graphics at the bottom of the doors, then the "formula 350 or 400" badges were replaced by the standard "firebird" fender badges. I dont think any engine call outs were available on a 76 formula with the large stripes.
I can dig out my old sales brochures & check if I'm wrong.
