1977 Chevrolet El Camino SS: Late-Year Prices, Retail vs. Dealer Invoice

This record's own key facts state that the 1977 El Camino power teams list three engines: the 250 six, the 305 V8 not for California, and the 350 four-barrel LM1, rated 170 net horsepower outside California and 160 inside it, the same two-tier California-versus-federal rating pattern this record's own engines section applies to the 250 six as well. Its overview field is empty for this year, so the key facts carry the year's introductory description on their own.

This record's own key facts also state that RPO Z15 SS remained an El Camino Classic option for 1977, with 15x7 Rally wheels, GR70-15 radial white-lettered tires, SS emblems, and upper body-side and tailgate stripes carried over from the prior year's package. The kit's late-1977 price schedule, covering vehicles built on and after June 27, 1977, lists the six-cylinder El Camino at $4,158.85 and the Classic at $4,293.85, with SS Equipment at $243.80 and the Conquista package at $138.00.

This record's own production rows carry two figures from a separate production-totals source, 54,321 El Caminos built for 1977 and 5,226 with SS equipment, and its own notes state plainly that no Chevrolet factory production report was found for this year, so both counts rest on the single production-totals source. Those same notes add that the SS figure had previously been held only as an unverified Wikipedia lead citing the very same page, a lead now resolved because that page has since been read directly.¹

This record's own prices section documents both retail and dealer-invoice figures for the six-cylinder models: $4,158.85 retail against a $3,439.52 dealer invoice for the base El Camino, and $4,293.85 retail against $3,551.57 dealer invoice for the Classic, the invoice figures explicitly noted as including the holdback retained for the dealer's own account rather than being a retail price. Its engines section documents the 250 six at two net-horsepower ratings, 110 outside California and 90 inside it, the 305 V8 optional and not for California, and the 350 LM1 at 170 horsepower outside California against 160 inside it.

This record's own transmissions section documents a standard three-speed limited to the 250 six alone, and Turbo Hydra-matic across every engine, standard with the 305 V8. Its options section runs to more than thirty individually priced line items beyond Z15 itself, from a $4 visor vanity mirror up to a $514 air-conditioning package, and separately documents the Z15 option's own dealer-invoice amount of $189.54 against its $243.80 retail price, the same split between retail and dealer-invoice figures this record's own prices section carries for the base models.

This record's own paint section lists solid and two-tone colors by code, several two-tone combinations cross-referenced to a specific upper-body color code such as code 29's pairing with upper color 22. Its specifications section documents curb weights of 3,752 pounds for the six-cylinder Standard El Camino and 3,784 pounds for the six-cylinder Classic, and a 116-inch wheelbase; its conflicts and unpublished leads sections are both empty for 1977, a gap it carries without substitution even though its own production figures rest on a single source rather than a separately sourced factory tabulation.
