The Chevy 350 engine is a beast of an engine that was first introduced in the ’60s. It is still used today and has been given many nicknames such as “the little old lady’s car” or “the workhorse.” This post will answer some questions you may have about the Chevrolet 350 engine.
The Chevy 350 is often confused with the more powerful 427. The only difference between them is that one has two extra cylinders, meaning it’s a big block engine and one doesn’t have any extra cylinders so it’s considered to be a small block.
What Is A Small Block Engine?
A Chevrolet 350 is also called a “small-block” as opposed to the larger (and much rarer) “big-blocks.”
Smaller engines are lighter than bigger ones, which means they’re easier on gas mileage because less fuel weight needs to be moved around for an even greater distance. Lighter cars can take turns faster and stop quicker too since their lower center of gravity aids in handling ability. So just under its size, a small block is more fuel-efficient than a big block.
The Chevy 350 engine was first introduced in the 60s and it’s still an important part of many people’s cars today.
Small Block Vs Big Block Engine?
A big difference between these two is mainly size: A Chevrolet 350 has four cylinders as opposed to eight for the 427 or six for 426 Hemi engines. Another major difference is that while there were some exceptions, most Chevrolets had steel blocks whereas Chrysler used aluminum blocks on their engines. Finally, small blocks usually have lower compression ratios because they’re designed with efficiency in mind but this can be changed if desired by adding higher octane gasoline such as 100+.
What is a 350 engine? The Chevy 350 engine has a 350 cubic inch (5.7 liter) small-block V8 and a 4.50 and 3.48 inch bores and strokes. Depending on the make and year of the car, horsepower can range from approximately 145 to more than 370.
A solid foundation is essential for a strong engine. Chevrolet knew that the strength and stability of the engine was crucial when they designed the LS V8. General Motors had to create different sizes of engines for different purposes since the LS engine was available in a variety of automobiles. Chevy was very aware of what they were doing when designing the LS engines. The V-8 engine family they created made good horsepower and torque. Chevy LS engines are known for being responsive to modifications. An intake/exhaust or cam swap will give you significant HP. Some people leave the stock heads on, and just have them replaced with a larger cam.
LS engines can produce over 440 hp without any headwork. Miata 1.8L engines weigh 348 lbs while LS engines are about 460 lbs. You are looking for an emissions-legal engine that produces 600 horses and can last for 100,000 miles. This crate engine is available at GM Performance Parts for a mere 24K. If a stock LS engine isn’t enough power, you can get an Edelbrock Supercharged LS416 Crate engine with 720 horsepower & 695 ft-lbs.
This 6.0 Liter truck-powered engine was based on the LS and was designed to bridge between the new LS small blocks for truck applications and the Big Blocks. The LQ4 engine’s major difference is that the heads are made of cast iron, not aluminum. The LQ4 engine was born when a set LS6 head was bolted to an iron block. Cast iron heads were used for the 1999 and 2000 model years, with cast aluminum heads for all other models. The powerful iron block and 4.000-inch bores for the GM L92 heads allow for serious horsepower at budget rates.
What makes a Chevy engine an LS?
General Motors designed the Gen III (LS) block as a “Y” block. Chevy designed the block for extra-long head bolts to thread deep into it. This reduces cylinder bore distortion as well as variation in the head bolt torque specification.
What is a 350-powered engine?
The Chevy 350 engine is a 350-cubic inch (5.7-liter) small-block V8 with a 4.00 or 3.48 inch bore. The horsepower ranges from approximately 140 to more than 350 depending on the year, make, and model of a vehicle.

Why is a 327 better than a 350
It’s more about “gearing” the vehicle than revs. A 327 with a shorter stroke would require shorter gears to get to its revs. Whereas a 350 with a slightly longer stroke and greater torque output will pull a slightly higher gear than the 327.
Is a 327 crank compatible with a 350?
The 327 crank won’t fit in the 350 blocks unless the crank is the post-67 327 crank with large bearings. You can use standard 327 parts like pistons with this crank. I would recommend using the 350 balancer instead of the 327 because it has better dampening properties.
