Is a Chevy 283 a good engine?
Even after the 327’s debut, the 283 made such a good base engine that it soldiered on through 1967. The 1.9:1 rod/stroke ratio is on the high side for an acceleration engine but great for an endurance or oval-track engine that runs at a high, constant speed.
What’s the horsepower of a Chevy 283 small block?
The Chevy 283 small-block consistently offered high-torque specs across all models. The 170 hp model offered the lowest torque with 275 lb.-ft. at 2200 rpm, while the 245 and 275 hp models offered the highest torque with 300 lb.-ft. at 3800 rpm.
How many cubic inches does a 283 crank make?
GM picked up on what racers were doing and added a 283 crank to a 327 (small journal) block,yeilding 302 cubic inches. I dont think those early 283 blocks could go to 4 inch bore though. this combo also gave birth to the 307, which was the opposite; 283 block with 327 crank.
What was the size of the Chevrolet small block engine?
The 265 cu in (4.3 L) V8 engine was bored out to 3 7⁄ 8 in (98.4 mm) in 1957, giving it a 283 cu in (4.6 L) displacement. The first 283 motors used the stock 265 blocks. However, the overbore to these blocks resulted in thin cylinder walls. Future 283 blocks were recast to accept the 3.875 bore.
How big is the spark plug on a Chevy 283?
The 270 and 315 hp models produced 285 lb.-ft. of torque at 4200 rpm. All models of the Chevy 283 had a bore and stroke of 3.875 by 3.00 inches. Additionally, the spark plug gap and point gap in all models were 0.035 inch and 0.019 inch, respectively.
How big was the stroke of the 283 Chevrolet engine?
151⁄200 in (95.38 mm) bore. The stroke of the 265 was 3 in (76.2 mm), like the 283. The 283, famous for being one of the first engines to make one hp per cubic inch, is also famous for being the evolutionary stepping stone that would later give rise to small blocks and to the “W” blocks, ultimately culminating in the Chevrolet big-blocks.

What kind of chamber does the stock 283 use?
The stock 283 used a 58cc chamber. The reason this is important is when we start plugging numbers into a compression ratio program—the short stroke makes adding compression difficult without going to domed pistons.
