code "F" and had a sales code of LV8. This was the first engine to use the smaller Rochester Dualjet two-barrel carburetor, the only carburetor used on the 260. Production of the 260 V8 ended in 1982 when the 307 became the only gasoline V8 in Oldsmobile's line. The 260 was designed for economy, and was the first engine option above the 4.1 ChevroletI-6, then later the 3.8 L Buick V6, which was standard fitment in many Oldsmobile models by the late 1970s. While the 260s were not very powerful compared to the larger 350 and 403 V8s, fuel economy was almost as good as the base V6. Compared to the V6, the 260 was also smoother-running, and far more durable. Most 260s were coupled to the Turbo Hydramatic 200 transmission, but a 5-speed manual transmission was also available in some vehicles.

It uses a bore (in common with the Buick 231 V6 and 350 V8) with a stroke. Some early 307s were painted GM Corporate blue, but most were painted satin black. It was used in most Oldsmobile models, as well as those from Buick, Cadillac, Chevrolet, and Pontiac. Every 307 used a four-barrel carburetor, which was a variant of the Rochester Quadrajet, usually the CCC (Computer Command Control) Quadrajet. The output of the wasn't particularly high in terms of horsepower. For example, the stock (non-high-output, VIN "Y") in the 1983 Oldsmobile 98 was a mere , although in that year a high-output model (VIN "9") was available producing a nominal , at approximately torque. The final 1990 configuration was rated at at 3200 rpm and of torque at 2000 rpm. The combination of good low-RPM torque, the Quadrajet four-barrel carburetor, and the THM-200-4R three speed plus overdrive automatic transmission having a lockup torque converter allowed for fairly good performance, and fuel economy considered reasonable for the era, even in the larger and heavier model cars. The engine is also known for its reliability, smoothness and quietness.
