The 1971 model year
Overview
Ford's 1971 Bronco brochure retained regular and Sport versions of the Wagon and Pickup. The standard 170-cubic-inch six and optional 302-cubic-inch V8 both paired with the fully synchronized three-speed manual; Ford did not list a Roadster or automatic transmission.

Year over year

- Ford's 1971 engine table rates the standard six at 100 gross horsepower and the optional 302 V8 at 205 gross horsepower.
- The equipment table lists a three-speed transmission as standard and no automatic option.
Worth knowing
Notable

- The brochure identifies the Dana 20 two-speed transfer case and a 4.11:1 standard rear-axle ratio.
Living with it
Reliability & ownership notes
- Verify whether a survivor began as a regular or Sport Wagon/Pickup before restoration because removable roofs and later trim changes can obscure its factory identity.
- Confirm the installed engine and transmission before ordering driveline or service parts; later conversions are common on first-generation Broncos.
