How much horsepower can you get from a Chevy 283?

In all, five separate versions of the 283 were produced between 1957 and 1967. Horsepower was offered as little as 185. But the 283 could be boosted to a maximum 315 horsepower, which is a remarkable feat given its displacement.

Are Chevy 283 a good motor?

Even after the 327’s debut, the 283 made such a good base engine that it soldiered on through 1967. With its short 3-inch stroke, a 283 can rev as if there’s no tomorrow, but the small bore restricts adding really large valves and, hence, ultimate breathing potential.

Can you stroke a 283 Chevy?

It can be done, but it’s not money well-spent. Speed-O-Motive sells a small-journal 3.75″ stroke crank. It was designed to turn a 327 into a 383. You would need custom (expensive) pistons for the small-bore 283 block.

How much horsepower does a 1957 283 have?

The 1957 “Fuelie” 283 came in two varieties: With hydraulic lifters and 9.5:1 compression, it produced 250 horsepower; with solid lifters and 10.5:1 compression, it made 283 horsepower.

Can you put 350 heads on a 283?

For a 283, DO NOT use heads meant for a 350, or even the 327 Camel Hump/Double Hump heads (unless you have some serious domes on the 283 pistons). The smallest chambers the Double Humps had, were the 461X castings with 62 CC’s; the rest had 64 CC’s. 350 heads could have as large as 76 CC chambers!

What is the difference between a 283 and 327?

A 283 . 60 over is a 292 cubic inch. But yes if you use a stock bore 327 with 383 crank you get a 301, but you have to change the pistons so the pin height is right. Also 283 cranks have a round flange where 327 have a notched flange on the crankshaft.

How much can I bore 283?

You could bore a 283 to 4″,and get a 301. However it would take a lot of $$$ to get 300 ponies out of it. In a big Impala,I would consider a 350,or a 400 cu.in. It would bolt in,and you would have a lot more torque,without having to rev it to high heaven.

How much compression should a 283 have?

The 283 is a V-8 engine that has a bore and stroke of 3.875 by 3.000 inches, 283-inch piston displacement and either an 8.5, 9.5 or 10.5 compression ratio, depending on the configuration. The engine was made from 1957 to 1960.

What are the best heads for a 283?

If sticking with the 283, 305 HO heads would be a great choice on a 283. The “HO” heads had 1.84 intake valves, whereas normal 305 heads had only 1.72. If you look around, you can often find -416 or -601 heads for dirt cheap.

Is 283 a good engine?

Even after the 327’s debut, the 283 made such a good base engine that it soldiered on through 1967. With its short 3-inch stroke, a 283 can rev as if there’s no tomorrow, but the small bore restricts adding really large valves and, hence, ultimate breathing potential.

What size carb for 283?

A 500 CFM carburetor would be a perfect size for your 283. The only reason for going to a 600 CFM carburetor would be if you were planning on major engine modifications or swapping a bigger motor in the future. I enjoy tinkering around with the 600 CFM Holley on my ’55. However were I to buy a new carburetor it would be an Edelbrock Performer.

Which Cam for a 283?

Back in the day, we ran the Duntov 283 “fuellie” cam, or 8-18 cam. ( named for the valve settings). It’s a solid lifter cam, not near as thumpy as the 30-30, and better low end, but like most solid lifter cams it comes on harder at higher rpm’s.

What are Chevy small block engines?

The Chevrolet small-block engine is a series of V8 automobile engines used in normal production by the Chevrolet Division of General Motors between 1954 and 2003, using the same basic engine block. Referred to as a “small-block” for its comparative size relative to the physically much larger Chevrolet big-block…
