For 1973, GM's line of full-size trucks was redesigned and updated. A tilt-steering wheel became optional.Although rear-wheel drive Blazers were manufactured until 1982, the majority sold were four-wheel drive. Since 1981 (in the wake of the 1973 Arab Oil Embargo and the 1979 energy crisis), Chevrolet and GMC used the smaller displacement 305s with a 9.2:1 compression ratio. These engines produced nearly as much torque as the 350. However, these power plants were underpowered and prone to detonation (engine knocking), especially with the electronic spark control module. To achieve the 9.2:1 compression ratio, the cylinder head chambers were smaller, measuring 56 cc instead of 76 cc.
