Chevy C10/GMC K10 Second Generation
A new, more modern look came in 1967, along with a new nickname: “Action Line”. It was with this revision of the C/K truck that General Motors began to add comfort and convenience items to a vehicle line that had previously been for work purposes alone. Updated styling features for the 1967 Chevy Pickup trucks came with new body sheet metal that helps fight rust and a pickup box made of double-walled steel. The majority of 10 and 20 series Chevrolet trucks from 1967 to 1972 were built with a coil spring trailing arm rear suspension, which greatly improved the ride over traditional leaf springs. However, the leaf spring rear suspension was still available on those trucks, and standard on 30 series trucks. The front suspension on all Chevrolet trucks were independent front suspension with coil springs. GMC models came standard with leaf springs with coils springs optional; all four-wheel drive models (Chevrolet and GMC) had leaf springs on both axles. 1967 was the only year for the “small rear window” (RPO A10 offered a large rear window as a factory option). The standard drivetrain came with a three speed manual transmission and one of two engines; the 250 in³ straight six or the 283 cu in (4.6 L) V8. The optional transmissions were the four speed manual, the Powerglide and the Turbo-Hydramatic 350 and 400. The 292 six and the 327 in³ V8 were the optional engines. The 1/2 ton trucks came with a 6 x 5.5″ bolt pattern, the 3/4 and 1 ton trucks came with an 8 x 6.5″ bolt pattern.
1969 Chevy C10/GMC K10 Differences
The 327 c.i. V-8 engine was enlarged in 1969 to 350 CID (stroke increased from 3.25 to 3.48) with a net horsepower rating of 195-200, depending on emissions package 255 hp (190 kW), 350 cu in (5.7 L). Along with the new engines came a new grille design for Chevrolet trucks and a more upright hood for both Chevrolet and GMC trucks. A utility variant, known as the K5 Blazer, was also introduced with a shorter wheelbase of 104 inches (2,642 mm). The GMC version, known as the Jimmy, was introduced the same year. Some internal cab changes were also made, most notably the switch from a hand-operated parking brake to a foot pedal, and a more modern looking two-spoke steering wheel with plastic horn button replaced the previous year’s three-spoke wheel with chrome horn button. Also new this year were upper and lower side moldings, which added another two-tone paint option. These were standard on CST trucks, and optional in any other trim level.
