Really, history? For what purpose? You think a Chevelle buyer wouldn't know this? At least get the history right.

The Chevelle was introduced on September 26, 1963 as a mid-sized vehicle for the Chevrolet fleet. When introduced in 1963, its 327 cubic-inch V8 engine producing 300 horsepower was no match for the 389 cubic-inch V8 that the Pontiac GTO concealed under its hood. In the years that followed, Chevrolet would answer the challenge with larger, more powerful engines. In 1965, Chevrolet unleashed a limited edition 396, known as the Z-16 package. The 201 examples that were produced featured 375 horsepower, highly-modified suspension and power-assisted steering, and anti-roll bars in the front and rear.

Chevrolet was catching up in the horsepower battle. In 1966, the 283 and 327 cubic-inch engines were no longer being offered. Rather, the 396 became the standard engine with the horsepower outputting between 325 to 375 depending on the configuration. The greater the horsepower the vehicles received, the greater the need to modify the other components of the vehicle. All Chevelles were outfitted with stiffer springs and shocks to counter handling problems. The SS name was switched to SS396 to highlight the 396 cubic-inch engine lurking underneath the hood. A new bumper, roof line, and dual hood scoops were applied to the vehicle to give it an updated and more aggressive look.

(1) The 283 and 327 were still offered, just not in the SS396 but that's not mentioned.
(2) The 396 became the standard engine in the SS396 series only but no distinction made here either.
(3) All Chevelles were not outfitted with stiffer springs and shocks, all SS396 Chevelles were.
(4) The SS name was not switched to SS396, the series was changed from Malibu SS to SS396.

The 1967 Chevelle was available in several trim levels including the Chevelle 300, Chevelle 300 Deluxe, Chevelle Malibu, or Chevelle SS396. Each configuration could be ordered with a six cylinder (except SS) or V8 engine. Body style included 2 door sport coupes, 2 door sedans, 2 door convertibles, 4 door sedans, 2 door wagons, or 4 door wagons. Interiors could be optioned with either bucket seats or bench seats and were available in a variety of colors.

(1) The 2 door wagons were discontinued in 1966, 1965 was the last year for the 2 door wagon.
(2) Interiors were not optioned with bench seats, bench seats were standard in ALL Chevelles.
(3) Only Malibu sport coupes, convertibles, and pickups as well as SS396 sport coupes and convertibles could order bucket seats as an option.

To complement the wide variety of available colors were several drivetrain combinations that could be opted for on the 1967 Chevelle. Base power included one of two available six cylinder engines. Buyers who wanted more power could select a V8. Big blocks were in abundance with the regular availability of a 396 cubic inch engine which boasted 325 horsepower, or optional 350 hp and 375 hp configurations. Manual transmissions were either 3-speeds or 4-speeds, while automatic transmissions were either the 2 speed Powerglide or 3-speed TH400.

About 404,000 1967 Chevelles were produced.

The figure of L35 engines cited were optional L35 engines available as options ONLY in the two V8 El Camino series, 13480 and 13680. The El Camino was the only body style that could optionally order the L35, L34, or L78 engine.  There were 63,006 SS 396 Chevelles sold in 1967 (59,685 sport coupes and 3,321 convertibles). The two optional engines (L34 and L78) were available in the SS396 series as well as the El Camino. The L34 sold 17,176 units and the L78 sold 612 units for a total of 17,778 optional 396 engines. Even assuming NO L34 or L78 was installed in the El Camino (which, of course, many were), that leaves 45, 218 SS396 Chevelles being ordered with the base L35 engine.

The '38' series number was used in both the SS396 and the Concours station wagon. Minor point, but not all 1967 '138' Chevelles were SS396 cars.

Bottom line, if you feel the need to cite the history of a car, at least get the history correct.
