Engine options for the 1966 C10
Engine options available to buyers were categorized by two main types: inline-sixes for economy and durability, and small-block V8s for more power. The following list outlines the primary choices commonly found in 1966 C10 pickups.
- 230 cu in inline-six (Turbo-Thrift) — standard on base models
- 250 cu in inline-six — available as an option on higher trim levels

Notes on availability and performance
Availability of each engine could vary by body style, cab configuration, and regional market. The inline-sixes were favored for durability and fuel efficiency in fleet and work applications, while the 283 and 327 V8s offered more torque and horsepower for customers needing extra performance.
