Since the SS was an option rather than a series after 1968, you’d need to have a build sheet, window sticker, or other documents to validate an El Camino SS 454’s heritage. The El Camino was a body style of the Chevelle, not a separate series. This potent pickup is available here on eBay where $19,200 has yet to crack the reserve, but you can Buy It Now for $29,500. From a garage in Walker, Louisiana, this truck presents as a nice survivor that has been cleaned up in some of the pics. The seller offers a nice ’71 El Camino which we’re told is a real-deal SS 454, but there’s no documentation (or any seller details for that matter) to back it up. Mechanically, it could be equipped any way you could order a Malibu, including the Super Sport option and the hot 454 cubic inch V8 (beginning in 1970). From 1964 to 1987, the El Camino was a “gentleman’s pickup” version of the mid-size Chevrolet Chevelle.
