Why It Matters
The Pontiac L75 455 engine assembly covers the late 455 four-barrel path used by the 1976 Firebird Trans Am 455 four-speed branch. It should be kept separate from the earlier 455 HO and SD-455 engines and verified with VIN, engine stamp, date, emissions-equipment, and paperwork evidence.
