Chevy’s Use of EFI
Chevrolet started using EFI (Electronic Fuel Injection) in the year 1982. This marked the beginning of Chevy’s transition from carbureted engines to fuel-injected engines, which offered smoother running, easier starting, reduced need for adjustments or maintenance on the cylinder head, as well as a more powerful and efficient RPM curve for every body style.
So, the year 1982 is when Chevy began incorporating EFI into their vehicles, signaling a significant shift in their engine technology.

When did Chevy switch to EFI?
As mentioned in a previous column, Chevrolet became the first manufacturer in 1957 to release a Rochester fuel-injection unit as an option on its full size passenger cars and the two-seater Corvette. This injection unit produced one horsepower per cubic inch with its 283 cu. in. V8 that delivered 283 horsepower.
How many 1957 Chevys had fuel injection?
1.5 million Chevy were made in 1957. Only 1,530 had fuel injection and it’s estimated that only 50 or less were in utility sedans! This is a no frills, lightweight muscle car.
What year did GM start using fuel injection?
1957
GM introduced its first fuel-injection model to the automotive market as an option in 1957. It was in the options packages for many vehicles that year, but the early design didn’t have all the bugs worked out, so it was dropped from all models except the Corvette the very next year.
What year did fuel injection replace carburetors?
1990s
Since the 1990s, carburetors have been largely replaced by fuel injection for cars and trucks, but carburetors are still used by some small engines (e.g. lawnmowers, generators, and concrete mixers) and motorcycles.
When did Chevy trucks stop using carburetors?
Best Answer. Chevrolet introduced a mechanical fuel injection option, made by General Motors’ Rochester Products division, for its 283 V8 engine in 1956. It has become the primary fuel delivery system used in automotive engines, having replaced carburetors during the 1980s and 1990s.
What year did GM stop using throttle body injection?
Throttle body injection started in 1986 on the 350 and 305 and went all the way until about 1995 and some 1996 350s and 305s.
When did Chevy fuel inject the 350?
Computer-controlled emissions systems became standard on all Chevy 350 engines in the early 1980s, with throttle body fuel injection becoming standard around 1988.
What year did GMC stop using carburetors?
All the big 3 were pretty much done with carburetors by 1990. It was a gradual phase out through the 1980s. The J body GM cars had it in the early 1980s. Ford and Chrysler lagged GM a bit, but by 1990 Fuel injection was standard on just about everything.
When did c10 go fuel injected?
COG Executive Director. One C-10 was fuel injected in 2010.
What was the last year for carbureted engines?
1991
In fact, the carburetor was one of those key advances that made it possible to put an explodey contraption on top of a wheeled cart and semi-reliably travel down the road. But for all things an end must come, and the last carbureted passenger vehicle rolled off an assembly line in 1991.
