Here’s what you need to know about building a 408 stroker LS engine. You’ll learn how to increase the power and performance of your engine.
Bigger is Better. There’s something about the unoccupied space between piston walls, about the unseen volume inside a combustion chamber that just screams to be filled up with more. But there’s a danger lurking in aluminum-heads and iron blocks alike that says you can have too much of a good thing.

When it comes to building your own car or engine, there are plenty of things that you can do at home and out in the garage. The most important thing though is knowing where to start.
The first thing that you need to do is make sure that you have all of the right tools for the job. You don’t need to go out and buy everything at once; just start off with what you think will be most useful and add more as time goes on. Here are some basic tools that should get you going:
Socket Set – A good set of sockets will allow you to take off all of the bolts on the engine block and heads without having to worry about stripping them.
Pliers – Pliers can be used for removing spark plugs and other small parts that might break if you use regular pliers. It’s also nice having something that won’t scratch up your hands if you need to hold onto something hot!

How to Build a 408 Stroker LS
Building a 408 stroker LS is not for the faint of heart. It’s not as simple as bolting on some parts, but it can be done with the right knowledge and planning.
The first thing you need to know is what kind of engine you’re working with. Are you converting an existing engine or building one from scratch? If you’re converting an existing engine, then you’ll need to make sure that your components will be compatible with each other and will work properly together.
If you want to build a 408 stroker LS from scratch, then read on below for more information about what parts are needed and how much they cost.
How Much Does It Cost
A complete 408 LS stroker kit can cost anywhere between $1,500 and $2,000 depending on which brand name parts you choose. For example, if you want to use Callies connecting rods or Eagle crankshafts in your build, then expect to pay more than average because these brands are considered “premium” brands in the racing industry and cost more than say AutoZone or O’Reilly Auto Parts brand names.

Building a 408 LS Stroker is not an easy task. It takes a lot of time and patience. In this article, we have discussed the most common questions asked by people who want to build their own 408 LS Stroker engine.
Building a 408 Stroker LS Engine: What You Need
Before you start building your own 408 LS stroker engine, here are some things that you will need:
Block – The block is the foundation of your engine. It’s where all the other parts are attached to and from where they receive their power. For building a 408 LS stroker engine, you will need an aluminum 5.7L block with six bolt mains similar to the ones used for other GM trucks including Silverado and Sierra 1500 trucks as well as Corvette Z06 models. The best thing about using these blocks is that they are relatively cheap compared to other alternatives like aftermarket blocks or even OEM blocks used on other cars and trucks. However, if you want to build a more powerful engine with more displacement then it might be better to use an aftermarket block but that will cost you a lot more than using an OEM block because aftermarket blocks are much harder to find and
Building a 408 LS engine isn’t just another project. It requires a lot of time, money and patience. Building the engine right the first time is vital to having an engine that will last for years to come. If you want to make big power, building a 408 LS stroker is one of the best ways to do it.
Building a 408 LS Stroker Engine
Building a 408 LS stroker engine can be done in a variety of ways. The first step is choosing the block and crankshaft combination that will work best for your application. You’ll also need to decide on whether or not you want forged pistons or cast pistons and what compression ratio you’d like for your build. Once those decisions are made, then it’s time to choose the camshafts, cylinder heads and induction system that will help your motor make more power than ever before!
Choosing Block And Crankshaft Combination
There are several different blocks available for building a 408 LS stroker engine including:
A stock 454 block can be used with minimal machine work but will limit how much displacement you can achieve. If you’re planning on making over 500 horsepower, then this may not be an option for
The 408 LS is a great engine for street and strip applications. It retains the same bore size as the LS3, but has a longer stroke, giving it a displacement of 376 cubic inches. The 408 LS can be bored and stroked to achieve a range of displacements that include 402 cubic inches, 408 cubic inches and 427 cubic inches. The 408 LS offers more displacement than the 383, but comes with the same power potential as the LS3.
The 408 LS was never offered by GM, but it is possible to find used factory parts for this engine. The camshaft and timing chain are typically made from steel, which must be upgraded with aftermarket parts if you intend to increase horsepower beyond 500 hp.
For those who want to build their own 408 LS engine from scratch, there are many companies that sell crate engines capable of making up to 700 hp at the flywheel. A stock 408 LS block can easily handle over 700 hp if built properly with forged internals and head studs instead of bolts holding down the heads on each side of the block
A stock LS6 block can safely handle up to 480 horsepower. The LS6 block is based on the 5.7L engine and was used in the Corvette Z06 and Cadillac CTS-V. You can take an LS1 or LS2 block and make it into an LS6 block by bolting on the pistons, heads, camshafts, intake manifold, headers and other parts from an LS6. This will give you over 500 horsepower with stock components, but you can go even further by adding forged internals like rods and pistons which are stronger than those from the factory. The best part about building an LS is that there are plenty of aftermarket parts available for performance upgrades such as ported heads, cold air intakes and headers for exhaust systems which offer better flow than stock components
If you’re building a 408 stroker LS, you’re probably wondering how much horsepower it will make. The short answer is, it depends on the parts you use and how many cubic inches you build.
Here’s a look at some of the most popular 408 stroker LS builds:

You can build your 408 from scratch, or buy a kit from one of our partners. It’s up to you! Either way, we’ll walk you through every step of the process with easy-to-follow instructions and videos.
408ci LS Stroker Builds – How Much Horsepower?
For the most part, a 408 LS stroker motor is going to be able to make around 400 HP. The exact amount will depend on how much you build it and how well you build it.
The first thing that needs to be determined is what type of camshaft you want to use in your engine. A larger camshaft will make more power but also creates more torque which can cause problems with shifting and acceleration. In order to get the best of both worlds, you’ll want to try and find a camshaft that works well with your transmission and rear end setup. Also, don’t forget about your cylinder heads and valvetrain when choosing a camshaft because they play a big role in performance as well.
The next thing that needs to be determined is whether or not you’re going to use an aftermarket block or if you’re going to go with a factory block. The aftermarket blocks will give you better cooling options and allow for larger bore sizes without having to worry about clearance issues with other parts on your engine like the oil pump pickup tube or distributor shaft bearing caps. However, factory blocks can save some money because they often come from wrecked vehicles at junkyards
The LS engines are great for building high horsepower engines. The engine is designed to handle a lot of power without breaking.
It is possible to build a 408 LS1 but it will cost you a lot of time and money. The biggest problem with building a big engine like this is getting parts in the right places at the right time. You can buy parts as they come in, but that means you have to wait until they become available, which could be months or even years after you start your build.
Building an LS engine is not like building an old school engine where everything was made locally and accessible. To find all the parts you need for an LS build, you have to travel around the country looking for parts stores that carry them. Then when you get home and start putting it together, there might be something else missing because it wasn’t available when you started building your motor.
There are certain things that are required on these engines to keep them running well and safe – things like camshafts, valve springs, timing chains (or gears), oil pump pick up tubes, etc… Those items may not be available from one supplier so you’ll have to order from two or three different companies just to get one component.
