* Engine: This is the most significant difference. The 1970 Z28 came *exclusively* with a 350 cubic inch (5.7L) small-block V8, specifically a high-performance version with a solid lifter camshaft. Standard Camaros offered a wider variety of engines, including smaller six-cylinder options and less powerful V8s.
* Suspension: The Z28 had a performance-tuned suspension with stiffer springs, shocks, and sway bars designed for better handling. Standard Camaros used a more basic suspension setup geared towards comfort.
* Brakes: The Z28 often featured upgraded brakes compared to standard Camaros to better handle the increased performance. This might include larger discs or better calipers.
* Exterior/Interior: While some visual elements could be optioned on both, the Z28 generally had specific exterior badging (including the iconic "Z28" emblem) and might have offered unique interior options (like specific upholstery or gauges). However, many of the visual cues could be replicated on a standard Camaro through custom ordering.
* Transmission: While both offered various transmissions, the Z28 was typically offered with higher-performance options that could better handle the power and torque of its engine.
In short, a 1970 Camaro Z28 was a factory-built performance version of the Camaro. A standard 1970 Camaro could be ordered with various engine and options, some of which might approach the performance of a Z28, but the Z28 represented a specific, pre-packaged performance build from the factory.
