When it comes to the 1967 Camaro's performance potential, 

the aforementioned engine choices are only the tip of the iceberg. 

Chevy also made care to incorporate a variety of special engines for some of its more upscale trim packages. 

The first was the 1967 Camaro Z/28, which was created especially for the SCCA Trans-Am Series in America.

 It had a 4.9-liter small block V8 engine that was capable of producing 290 horsepower and 290 pound-feet of torque at its highest capacity.

If you're wondering why this unique engine is less potent than other standard features, it's because the Z/28 was designed to participate in 

the Trans-Am Series' 5.0-liter displacement class while simultaneously maintaining a power rating of less than 1 horsepower per cubic inch.
