The 1968 Camaro engine options defined the car's identity, transforming it from a stylish pony car into a legitimate performance machine. Buyers that year faced a significant decision, as Chevrolet offered a wide spectrum of powerplants to suit different driving styles and budgets. Understanding the specific engines available is crucial for enthusiasts today, whether for restoration, purchase, or historical appreciation. This guide breaks down the available powertrains for the model year, detailing the differences between base units and high-performance offerings.
Base and Optional V8 Engines
Most 1968 Camarros rolled out of the factory equipped with one of two standard V8 engines. The entry-level option was the 230 cubic-inch inline-six, which provided adequate power for everyday driving and fuel efficiency. For those seeking more authority without the premium of a big-block, the 327 cubic-inch V8 was the popular intermediate choice. This unit came in various states of tune, with the base version producing 250 horsepower, while the more powerful variants pushed output toward 300 horsepower.

327 cubic-inch V8 (standard optional)
350 cubic-inch V8 (introduced late in the model year)
Late in the production cycle, Chevrolet introduced the 350 cubic-inch V8 as a new option. This engine would go on to become an icon of reliability and power, but in 1968, it was still establishing itself. The 350 offered a strong balance of torque and efficiency, making it a compelling alternative to the smaller V8s for buyers who wanted modern displacement without the thirst of larger motors.
High-Performance Powerhouses
For the driver seeking serious performance, the 1968 Camaro engine lineup included formidable factory supercharged options. The top-tier choice was the L78 327 cubic-inch engine, producing an impressive 350 horsepower thanks to a high-lift camshaft and solid lifters. This unit was designed for enthusiasts who wanted to drag race on the street and required premium fuel to handle the increased compression ratios.
L78 327 — 350 hp
L36 327 — Hydramatic auto only
L79 327 — Special performance package
L89 327 — Lightweight aluminum heads
Another legendary option was the L89 package, which replaced the heavy iron heads with lightweight aluminum versions. This modification saved significant weight in the front end, improving handling and acceleration despite the engine remaining a 327 cubic-inch unit. These high-performance models represent the peak of the first-generation Camaro's engineering, catering to the burgeoning muscle car market.
The Big-Block Contenders
While the 327 dominated the upper-middle range, buyers with deeper pockets could opt for the massive 396 cubic-inch big-block engine. Known as the "Turbo-Jet," this large-displacement powerhouse was reserved for the most aggressive driving ambitions. The 396 delivered massive low-end torque and a brute-force presence that smaller engines could not match, making it the choice for drivers who prioritized straight-line speed.
The 396 was available in multiple configurations, generally rated between 325 and 375 horsepower depending on the specific components and carburation setup. This engine was mated to heavy-duty transmissions and differentials to handle the immense power delivery. Owning a 1968 Camaro with the 396 is a reminder of the era when Chevrolet was unapologetic about building cars meant for high-speed cruising and quarter-mile blasts.
