#You â€œcanâ€ get 500HP out of a 350 BUT because it is a small cubic inch engine it IS going to be peaky and won't have much torque
. ... You do NOT want a â€œchain sawâ€ of an engine in your car! Chain saws make NO torque and they only way they can cut wood is at wide open throttle at their peak RPM.

Moreover, how much horsepower can I get out of a 350?
a typical 350 Chevy can make upwards of 350 - 375 HP before you exceed the reliability of the components. For a big block with the same stock components it can make in the area of about 400 to 475 or so HP and handle upwards of about 500 HP before you exceed the reliability of the stock cast pistons.
Long story short, can you get 400hp out of a 350? A: You can get 400 hp out of a small block 350 and keep it streetable. First, stay away from the 305 heads. They actually don't flow very well, and since they're cast iron, you can only go up to 9.5:1 compression.
Along, how much horsepower do headers add to a 350?
The length of the primary tubing determines the effective rpm range, but headers can be worth 15-20 hp on the right application. Run on our restrictive two-barrel 350, the headers improved the power output to 248 hp and 365 lb-ft of torque, with consistent gains through the rev range.
Is a 400 small block better than a 350?
A small block 350 and a 400 have an identical block design. Most accessories will fit either engine. The major difference is found in the casting numbers and the way they are balanced. Most 350 cubic inch engines are internally balanced whereas the 400 engines are not.

The more cubic inches the engine has, the more airflow the heads have to deliver. A head with 180 or 185cc intake runners will work well on a typical 350 Chevy street engine that makes 400 to 450 horsepower.
Re: How much can a stock bottom end handle Assuming it was correctly rebuilt, a completely stock bottom end - main bolts, cast crank, stock rods, cast pistons is good to around 350 HP.
So a . 030" over 350 is actually a 355 cubic incher, and at 1HP per cubic inch for a mild build, we would get 355 HP.
The four-bolt main 350 with two-barrel carburetor came with 8.5:1 compression, and was good for 145 horsepower at 3,800 rpm and 250 foot-pounds of torque at 2,200 rpm. 350s equipped with four-barrel Quadrajet carburetors produced 170 horsepower at 3,800 rpm and 255 foot-pounds of torque at 2,800 rpm.
The Chevy 350 engine is a 350 cubic inch (5.7-liter) small block V8 with a 4.00 and 3.48 inch bore and stroke. Depending on the year, make and model of a car, horsepower ranges from approximately 145 to more than 370.
With the stock Vortec heads, the low-compression 400 managed to make 376 hp and almost 450 lb-ft of torque.
In general, a quality set of headers should provide an increase of approximately 10-20 horsepower, and if you're restrained with your right foot, you may even see an increase in fuel mileage.
While it may not make a drastic difference such as installing a turbo or supercharger, investing in high-performance headers can increase the engine's torque, and subsequently the car's horsepower. Depending on the type of car you have and exhaust system, upgrading the headers can result in a 5% increase in horsepower.
The most powerful small block ever produced is the LS9 engine used in the current Corvette ZR1. It is rated at 638 horsepower, making it the most powerful engine ever produced by GM for a regular-production car.
Evening all... the 400 is a great motor especially for street use. It has the power where you really need it. As far as overheating goes, make sure you have a good cooling system and you should be fine.
Stretching a 350 to 383 inches has been a common practice for the best part of 20 years. The question here is, can we go more? In terms of bore diameter, there is not much room to go more than 30 over, although a sonic tester can find blocks good for as much as 60 over.
Changing the camshaft on a small block Chevrolet 350 engine is a project that requires methodical disassembly, inspection and reassembly of many parts on the engine. Since the camshaft and lifters are internal components, several external parts will need to be removed first in order to complete this task.
Surprisingly, the 454 laid down an impressive 330 horsepower and 475 pound-feet of torque. Naturally, the truck-based 454s were tuned for torque, so having nearly 500 pound-feet wasn't a big surprise. But like any stock engine, there was tons of power left to be squeezed out.
Aluminum heads will dissipate heat faster. This allows for higher Compression Ratios with less risk of Detonation. The cooler head also delivers a cooler air/fuel mixture to the combustion chamber. Cooler air is denser and can make more power.
"Double-hump" heads were found on many of its high-performance engines in the 1960s and early 1970s. They were manufactured with larger intake and exhaust port volumes and valves for the period, and engines equipped with them had output ratings of more than 350 horsepower.
A 383 that will see 5000 rpm max, a 170 ccc head will work just fine. A 383 that want to go to 7000 rpm then 210 cc head is what is needed.
A 2-bolt main with aftermarket studs is stronger than a 4-bolt main block, less prone to crack, and can take up to 600 HP on a seasoned block.
Stock cast pistons will limit you to 5800rpm, but cast pistons will hold more than 500hp. It is good to 7000 for forged pistons.
It means that the cylindar has been bored 0.030 or 0.060 over size in inches. If you look at a foreign car the over size measurements are in mm and are smaller.
The machine work is usually in the $250~300 range for bore & hone to size ( including cam bearing install if desired). Bottom edges of block may need light relieving to clear rod bolts.
The 383 stroker engines have been reported to achieve 330 horsepower with 410 foot-pounds of Torque, 395 horsepower with 410 foot-pounds of Torque and 395 horsepower with 410 foot-pounds of Torque.
Registered. Actually, the LS style engines have six bolt mains. Four are vertical and two are horizontal and come in from the side of the block.
Any time you increase horsepower, torque and cylinder pressure, you increase crankshaft load. It would take quite a bit more stress to rip-out 4 bolts than it would just 2, so that's why the 4 bolt mains are stronger than the 2 bolt mains.
if in fact you are in ernest... the term 4 bolt refers to the number of crank Main Bearing cap bolts at each main cap on the block, two bolt is standard construction, but for extra heavy duty, like big trucks and racing applications extra bolt bosses are cast into the block and the caps are built to accomodate two ...
In the vehicle, it's more of a matter of "gearing" than revs. A 327 with it's shorter stroke would need shorter gears so it can GET to its revs, where a 350, with its slightly longer stroke and more torque output will pull a little taller gear than the 327 will. ... Never underestimate the importance of gearing.
Our fastest crate engine ever As the power behind the 2019 Corvette ZR1, the new supercharged 6.2L LT5 represents the pinnacle of Chevrolet's performance: It's the most powerful engine ever offered in a Chevy production vehicle.
A favorite for engine swaps, the 350 is very easily modded because of the abundance of aftermarket parts. And because so many Chevy 350s have been produced, they're affordable and easily attainable for swaps of all kinds. You can find a Chevrolet 350 in just about anythingâ€”on land, sea, or air!
