1968 Chevrolet Pickup & Suburban Fact Sheet

396 CID V-8 Option – High Torque V-8. Two versions were offered – a two barrel carbureted 9:1 compression ratio with 275 HP and a 4-barrel with 9.0:1 compression ratio and 310 HP. See Engine section for more information.

307 CID V-8 – Standard V-8. This, new for 1968 engine replaced the 283 CID V-8 as the standard eight-cylinder powerplant when a V-8 was ordered. It had a bore & stroke of 3.875 in. x 3.25 in for a displacement: 307 CID. The compression ratio was 9.0:1 giving 200 horsepower at 4800 rpm. A Rochester two-barrel.carburetor was fitted.

The Stepside models continued with the new for 1967 cab and sheet metal that had been touted for the advantages of lower exterior height and length, greater interior roominess, improved forward visibility. As for the Fleetside, the Stepside had all of the 1967 advanced safety features, better resistance to rust and corrosion,. Stepside bodies were con­tained between the rear fenders to provide a completely unobstructed load compartment. Floors were of durable select wood with recessed steel skid strips.

Rubber­ covered support chains held tailgate in open position to handle long loads. Stepside pickups were offered with either conventional 2-wheel drive or 4-wheel drive. All versions were available with 6½- or 8-ft. bodies and had the same chassis features as corresponding Fleetside models. A 9-ft. body is also offered on a 30 Series chassis with leaf-spring rear suspension and a maximum GVW rating of 7,800 lbs.

The sixth-generation Suburban and Panel came in only one wheelbase, 127.0″. A 3⁄4-ton C-20 Suburban was available and 4×4 K-10/K-20 models were also offered.

As in 1967, Suburbans were configured with a single driver-side door and two passenger doors. The rear-wheel-drive Suburban was also available as a panel truck for commercial purposes.The panel version could be had with either a closed rear section with no windows or with windows similar to the Suburban. The Panel had no side doors. All Panels, regardless of side windows, had windows fitted to the rear doors, unlike the Suburban, that had a station wagon-like rear hatch as standard., panel type swinging doors as an option.

The Suburban and Panel shared a large amount of mechanical commonality with its pickup-truck counterpart, sharing the same powertrain offerings. A 250-CID I-6 was standard, with a 292 CID I-6 offered as an option. 307 and 327 CID V-8s.

As in 1967, advanced engineering and redesigned power train con­figurations, reduced overall height by five inches while still retaining the normal transfer case to keep ground clearance of 12½ inches. In order to accomplish this, Chevrolet engineers relocated the 2-speed transfer case to a higher position and attached it directly to the transmission.

Cab and sheet metal were identical to that of Fleetside pickups. Frames however, are of heavier gauge steel to withstand the punishment of off-road use. Front and rear leaf­ spring suspensions were of a tapered leaf type which reduced inter-leaf friction and provided a smoother, more even ride. Three Fleetside and three Stepside pickup models were available with 4-wheel drive.
