Source note · September 25, 2026. A factory availability chart answers a narrower question than many truck listings ask. It shows combinations Chevrolet offered; it cannot by itself prove which parts were installed on a particular truck or whether they are still original.
What the 1976 chart shows
Chevrolet’s “Pickup / Power Teams” sheets dated January 16, 1976 appear on printed pages 27–28 of the 1976 Chevrolet Truck kit (PDF pages 30–31). In that chart, the LF4 400 V8 appears for K10 and K20 pickups with the M40 automatic and NP203 transfer case. The LF8 454 V8 appears in C10, C20, and C30 pickup applications; no K-series pickup application appears in this Chevrolet chart. These are application statements from these dated sheets, not production totals or a claim about every GM vehicle.
What it cannot prove
A present-day engine, casting number, or seller description does not establish a truck’s factory configuration. For a specific vehicle, compare its VIN-consistent SPID label or build sheet with component markings, dates, and physical evidence. An equipment combination that fits the chart is possible; it is not automatically original to that truck.
