Oldsmobile used the popular LV2, a 307-cubic-inch (5.0 L) engine, commonly known by the VIN code “Y”, from 1980-1990. It was used by every domestic GM automobile marque except for GMC and Saturn.
All should have been roller lifter engines with the 7A heads. The last year for “Y” code 307s with the conventional valvetrain was ’84. (The “9” code continued to use the conventional valvetrain for another year or so.) Some say the 307 H.O. engine has a propensity for detonation, because Oldsmobile always ran high timing (20 degrees advanced).
A slightly larger 307 cu in (5.0 L) version was introduced in 1980. It uses a 3.8 in (97 mm) bore (in common with the Buick 231 V6 and 350 V8) with a 3.385 in (86.0 mm) stroke. Some early 307s were painted GM Corporate blue, but most were painted satin black.
The 307 stayed carbureted until the bitter end of production (1990). Every 307 used a 4bbl carb – there were no 2bbl models. The last of the GM 4-bbl engines and the last GM carbureted engine.
What car has 307 in it?

How much horsepower can you get out of a 307?
These are decent compression ratios and should help performance that will work with 91 octane pump gas. Combine these parts with a good 600 to 750 cfm Holley carburetor, an HEI distributor, and a set of long-tube headers and your 307 should make around 325 to 350 horsepower, perhaps even a bit more.
