Want this question answered?
I going for gas mileage on my 82 Chevy pickup. Should I rebuild the stock 305 or a 350ci. Remember looking for the best mileage.
It's lean. You have to figure out why.
If the 305 is uses a carburetor then adjusting the screws should lean it out. If the system is computer controlled, run a computer test to see what codes show up.
It sounds like some sort of lean condition. Perhaps a vacuum leak? Plugged fuel filter?
If the Buick 305 is really a Chevy 305, then the motor mounts will interchange with a Chevy 350.
Depends on what the 305 is in, a 305 camaro engine needs like a 9 tooth starter because the fly wheel is 12.75 inches in diameter with 50 some teeth. A 305 in a Chevy half ton will have like a ten tooth starter for the 14.25 inch diameter flywheel that has like 60 some teeth. All 305 engines before 1986 are the same they did have different flywheels for what ever Chevy put them in. 1986 and newer 305's had different cranks the flywheel bolts up different on a 1986 305 compared to a 1983 305.
Oldsmobile used Chevy 305's. 76 350 rocket 77 305 Chevy
There is no information on the internet about what the special feature of the Chevy 305 engine is, in fact, the Chevy 305 and 350 are interchangeable, one is just an older model.
impossible to gauge without knowing the vehicle car/truck, mileage and year, or modifications, after 1995 they came in trucks with 230 hp.
305 horsepower
It backfires because it's lean. The trick is to figure out why. Check your vacuum lines and anything that could obstruct fuel flow.
yes like 350 engine
