What should I do about my Chevy 305 engine?
The cam drive gear is of special concern on 305 engines. 305s manufactured before 1988 used a nylon-toothed cam gear to reduce noise. This gear is prone to failure and should be replaced with a solid steel gear. If replacing the stock water pump consider an electric version to reduce the workload of the engine.
What kind of car has a 305 engine?
Stodgy models like the Chevrolet Caprice, Oldsmobile Cruiser wagon, and the Buick Skylark used the engine, giving it a reputation as under powered. However, the 305 can also be found in the more demanding Camaro line as well as light trucks and vans. The engine was replaced by the Vortec 5000 in 1996.
Why is my Chevy 305 not running properly?
The stock headers further restricted air intake because of pollution concerns, though replacement Edlebrock or Vortec headers increase airflow while still maintaining proper emissions. Upgrade the air filter assembly with a modern unit to let the engine “breathe” more easily on the intake.
