How to Build a 383 Stroker Out of a 350

A 383 stroker is essentially a 350 block with a longer stroke. The extra displacement comes from boring the cylinders out and using a longer crankshaft. This combination provides more torque, which is ideal for street performance applications.

To build a 383 stroker out of a 350, you will need to acquire the following parts: -a 350 crankshaft with a 3.48” stroke -350 connecting rods with ARP bolts

-pistons designed for use with a 3.48” stroke crankshaft

  • Choose a 350 block that is in good condition to use as the foundation for your 383 stroker build
  • Bore the cylinders in the block to a finished diameter of 3
  • 75 inches
  • Install a 3
  • 48-inch stroke crankshaft into the block
  • Select 6-inch connecting rods for your build; these will work with most aftermarket pistons designed for a 5
  • 7-inch bore engine
  • Install pistons and rings onto the rods, and then insert the assemblies into the cylinders
  • 6 Set the compression ratio by selecting appropriate piston heads for your application; typical street performance applications work well with 10:1 compression ratio using 64cc combustion chambers 7 After setting cylinder heads, install camshaft and valvetrain components following manufactures instructions

How Much Does It Cost to Turn a 350 into a 383 Stroker

There are a lot of things that go into building a powerful and reliable engine, but one of the most important is displacement. Increasing the displacement of an engine can be done in a number of ways, but one of the most popular is by stroking it out to a larger bore size. This process involves boring out the cylinders and then installing longer pistons, which effectively increases the volume of each cylinder.

When done properly, this can provide a significant increase in power and torque. So how much does it cost to turn a 350 into a 383 stroker? It really depends on what route you take and how much work you’re willing to do yourself.

If you’re starting with a stock 350 engine, you can expect to pay around $3,000-$4,000 for all the necessary parts. This includes pistons, rods, bearings, gaskets, and more. If you’re starting with a performance-oriented 350 crate engine or something similar, you may be able to get away with spending less since some of the required parts may already be installed.

Doing the work yourself will obviously save you money compared to taking it to a shop, but it’s important to make sure that you know what you’re doing before attempting any major engine work. If done correctly though, turning your 350 into a 383 stroker can provide huge gains in power and performance – making it well worth the investment!

Can You Make a 350 a 383 Stroker?

The Chevy 350 engine is one of the most popular engines ever made. It’s been in production for over 40 years and has been used in everything from muscle cars to boats. The engine is incredibly versatile and can be modified to suit a wide variety of needs.

One popular modification is increasing the displacement by stroking the engine. This can be done by installing a longer crankshaft and/or using larger pistons. Doing this will increase the amount of power the engine produces, but it will also increase fuel consumption and emissions.

There are a few different ways to go about stroking a 350 engine. The most common way is to install a 383 crankshaft. This will give you an increase in displacement of 3.48 inches (88 mm).

Another option is to use 400 crank with 6-inch rods which will give you an extra 0.78 inches (20 mm) of stroke over the stock 350 crank. Or you could go all out and install a 454 crank which will give you a massive 4-inch (102 mm) stroke! Of course, there are other considerations when stroking an engine like this.

The pistons need to be replaced with ones that are compatible with the new crankshaft, and the connecting rods will likely need to be upgraded as well. The cylinder heads may also need some work in order to accommodate the larger piston size.

How Much Do You Bore a 350 to Make a 383?

If you’re looking to increase the displacement of your 350 small block Chevrolet engine, one option is to bore it out to 383 cubic inches. This can be accomplished by boring the cylinders out .030 oversize and using a 3.75-inch stroke crankshaft. With this combination, you’ll end up with an increase of approximately 33 cubic inches over a stock 350 engine.

One thing to keep in mind if you go this route is that you’ll need to use pistons that are designed for a .030 overbore. You’ll also need to use cylinder heads that have been machined for clearance with the larger pistons. Depending on what heads you’re using, you may need to have the valve pockets modified slightly for clearance as well.

If everything is done correctly, boring out your 350 to 383 cubes is a relatively simple and effective way to add some extra displacement without having to start from scratch with a new block.

How Much Hp Does a 383 Stroker Kit Add?

A 383 Stroker is a performance engine build that increases the displacement of an engine by stroking the cylinders. This means that the volume within each cylinder is increased, resulting in more power output. The most common way to build a 383 Stroker is to take a 350 cubic inch V8 and increase the stroke from 3″ to 3.75″.

This results in an increase in displacement from 350ci to 383ci. The extra displacement results in an increase in torque and horsepower, which is why many people choose to build a 383 Stroker for their performance needs. How much HP does a 383 Stroker kit add?

It really depends on what else you have done to your engine as part of the build. If you have added other performance upgrades like bigger camshafts or ported heads, then you can see gains of up to 50hp over a stock 350ci engine. However, if you are just building a basic 383 with no other modifications, then you can expect around 20-30hp gain over stock.

Either way, building a 383 Stroker is one of the best ways to get more power out of your small block Chevy!

What Makes a 350 Motor 383 Stroker?

A 350 motor 383 stroker is a high performance engine that is used in muscle cars and hot rods. This engine is made by taking a 350 cubic inch small block Chevy engine and boring it out to 383 cubic inches. This increase in displacement allows for more power and torque to be produced.

To further increase performance, the stroke of the crankshaft is increased from 3.48 inches to 3.75 inches. This combination of increased bore and stroke makes for a very powerful engine that is capable of producing a lot of horsepower.


The 383 stroker is a high-performance engine that can be built from a 350 block. The process involves boring out the cylinders, installing oversize pistons, and using a crankshaft with a 3.75-inch stroke. The resulting engine has more displacement than a stock 350, which translates into more power.

Building a 383 stroker is not for the faint of heart, but the rewards are substantial.
