History of the Oldsmobile 307 V8
A slightly larger 307 in?? (5 L) version was introduced in 1980. It uses the Oldsmobile 3.385 in (86 mm) stroke and a 3800-like 3.8 in (96.5 mm) bore. All 307s were painted black. It was used in most Oldsmobile models, as well as those from Buick, Cadillac, Chevrolet, and Pontiac. Every 307 was carbureted, and all used 4-barrel carbs. In fact, the 1990 5.0 L Olds V8 was the last carbureted passenger car engine on the market in the United States (excluding the 1991 Ford LTD Crown Victoria Police Interceptor 351 in?? and the 1994 Mazda pick up truck, the very last carbureted road use vehicle sold in the US).

The Oldsmobile 307 V8 was used in the following vehicles:

  • 1980-1985 Oldsmobile Delta 88
  • 1980-1984 Oldsmobile 98
  • 1980-1985 Oldsmobile Toronado
  • 1980-1990 Oldsmobile Custom Cruiser
  • 1980-1985 Buick Lesabre
  • 1980-1984 Buick Electra 225 / Park Avenue
  • 1980-1985 Buick Riviera
  • 1980-1990 Buick Estate Wagon
  • 1986-1990 Cadillac Brougham
  • 1986-1990 Chevrolet Caprice Wagon
Oldsmobile used the popular LV2, a 307 in?? (5.0 L) engine, from 1980 to 1990. It was used by every domestic GM automobile marque. Roller lifters were added in 1985.

There were two versions, the standard Y version produced just 140 hp to 150 hp (104 to 111 kW). The high-output 9 version was available in the 1983 and 1984 Hurst/Olds & 442. All LV2s feature a 4-barrel carburetor.

Y-version applications:

  • 1980-1985 Buick Lesabre
  • 1980-1985 Buick Riviera
  • 1986-1990 Chevrolet Caprice
  • 1980-1985 Oldsmobile Delta 88
  • 1980-1984 Oldsmobile 98
  • 1980-1985 Oldsmobile Toronado
  • 1980-1990 Oldsmobile Custom Cruiser
  • 1980-1981 Oldsmobile Cutlass
  • 1982-1988 Oldsmobile Cutlass Supreme

9-version applications:

  • 1983-1984 Hurst/Olds
  • 1983-1984 Oldsmobile 442
The LG8 was a modern 307 in?? 5.0 L High-Output derivative of the LV2 produced from 1985 to 1987. Performance modifications included improved intake and a "hot" camshaft. It was offered in the 442 version of the Oldsmobile Cutlass Supreme. Output for the first year was 180 hp (134 kW) and 245 ft??lbf (318 N??m). The addition of roller lifters for 1986 increased torque to 255 ft??lbf (332 N??m), while lowering the RPM at which peak horsepower and torque was achieved via a change in head design.
