1976 Chevrolet CKU246Z110145

Evidence status

Verified exact VIN across photographed SPID, build sheet, certification label, warranty material and dealer inspection. The build sheet establishes LF4 400 V8, Silverado and Camper Special equipment; it does not establish the later 454 as factory installed. The M38/M40 transmission notation difference remains unresolved.

Factory documents

The photographed VIN-matched build sheet identifies CK20903, Frost White exterior, Saddle interior, YE9 Silverado, Z81 Camper Special, 8,400-lb GVWR and LF4 400 V8. The SPID lists M40 Turbo Hydra-Matic while the build-sheet line appears to read “M38 CBC AUTO TRAN”; both readings are retained without resolving the difference. The separate certification label visibly repeats VIN CKU246Z110145 and reads 11/75, with 8,400-lb GVWR, 3,800-lb front GAWR and 5,560-lb rear GAWR. Warranty material and dealer inspection documents also repeat this VIN. Warranty paperwork records retail delivery November 25, 1975 through Hamby Motors in Hillsboro, Oregon; personal details are withheld.

Physical vehicle evidence

The source gallery shows the later engine bay and an odometer displaying 23,971.6. The dealer describes the later engine as a 454; photographs alone do not independently establish its displacement, originality, installation date or lifetime mileage.

Owner or seller statements

The seller said a dealer installed the 454 early in the truck’s life and estimated about 123,971 total miles. No installation invoice has been inspected, and the odometer display does not verify lifetime mileage.

Later research

Classic.com indexes a later exact-VIN appearance of the same truck. A Motorious dealer listing was preserved in the research archive but was unavailable in the September 26, 2026 live check. The factory-documented LF4 400 and dealer-described later 454 are separate evidence categories; the later displacement and installation history have not been independently established.

Open questions

Resolve the SPID M40 versus apparent build-sheet M38 wording, obtain an installation invoice or dated evidence for the later 454, and establish lifetime mileage, current custody and present component originality. No Spirit or Bonanza designation is visible on the readable SPID.
