Butler Performance Inc. - Crate Engine Builder Kits

Butler produces Pontiac power with its high performance Pontiac crate engines. All engines custom designed and tailored to your application. Get the power and performance you desire with an engine built, dynoed, blueprinted, and customized just for you. You can even get these engines in builder kits ready to assemble. These engines start with high quality parts form many top brands in the industry. Butler then puts them through the "Butler Process", a tried and true method established over many years in the performance and racing industry.

Please take time to see how our engine program works and we will be glad to answer any questions you may have.

Our crate engine and custom engine program has been a mainstay here at Butler. Our skilled machinists and builders have years of experience machining and building engines for all applications from all original looking numbers matching engines, performance versions of these, to high performance street strip muscle car engines that are big on power, fun to drive, and reliable on the street. Our reliability comes from attention to detail in our Butler Process when machining and prepping the block for assembly.

This process is the same no matter if you get a fully built complete engine or a ready to assemble builder kit that you or your choice of builder put together.

More About Crate Engine Builder Kits

Complete Engine vs Builder Kit

Complete Crate Engine (assembled)
Our complete assemble engines are fully assembled, blueprinted, and dyno tuned ready for installation when received. Our engines include a new aftermarket block, a Butler supplied core block (no core charge) or using your block. Using a customer block does have more steps as the block need to be shipped in or delivered where we can clean it, inspect it, and sonic test it to ensure we are starting with a block worthy of building. We can help with inbound shipping if needed. Those details will be covered more in depth if you decide to take this route in your build.
This type of build normally takes the longest time due to the added services of assembly, the complexity of dyno testing, and the added crating system used to transport a completely assembled engine.

Crate Engine Builder Kit
We can also do a complete engine (Long Block or Short Block) in unassembled kit form that you (or your shop) build. These lead times are short due to the extra services not being done in our shop. These kits can be produced in 14-16 weeks. These kits include the same blocks as a complete engine, fully machined and ready to assemble. We include all the same parts we would use in our assembly shop and ship to you or your chosen shop.

These kits are machined, and blueprinted ready for your final inspection/cleaning and assembly. Here at Butler we do not look at this as competition but rather we are partnering and will provide any technical details you may need including torque specs or assembly procedures and methods.
Custom Engine vs Butler Engine Package

We can build you any Pontiac engine imaginable and have probably already done it. These are custom engines and take a large amount of time on the front end designing and specing out the details. We also ensure that the combinations of parts will produce what is expected. Based on our build history and experience we can almost always deliver what is expected. These take a substantial amount of time testing and tuning. If this is the route you want to go then Butler can accommodate.

We have spent many years making each engine custom designed. During this time we have put together the combinations that simply work and deliver the HP and Torque levels expected. This has lead us to our Butler Packages.

These are more detailed on our site but you can basically select from these packages;

Stealth/Stock Appearing Crate Engines

450-600 HP Crate Engine and Crate Engine Builder Kits 

600-800 HP+ Crate Engines and Crate Engine Builder Kits

These have the same core components to make the power expected but still with basic options of carb/efi, paint color, and the other details to accent the look you are desiring. These packages have a faster setup time due to internal components are already spec'd and ready to select the final appearance options.
Your Block or BP Block

We can build your engine or kit using your block or a Butler supplied block. When using a customer block we can help arrange inbound shipping to make the process much easier. Once the block arrives we will thoroughly test it before machining. Butler also has core and aftermarket blocks available. Core blocks are thoroughly tested as well and there is no core charge. Aftermarket block are available in cast or aluminum. Aftermarket blocks are usually 505-535 cuin builds.

Lead Time

Our shop tries our best to keep a reliable build schedule where we can deliver as promised. With that being said, 2020 and 2021 have been trying times due to lack of parts and raw goods industry wide. There is nothing more frustrating for you the customer, and us the builder, than delays and missed delivery dates. This is why Butler Performance has a build schedule with slots scheduled throughout the year. This ensures that a customer that is ready with their deposit will be put into the schedule and given a delivery window they can depend on. As always, if there is anything that holds a build up, we will communicate and make any changes necessary to get back on schedule

Our current Engine Program is booked through the end of 2021 and we will start to schedule for 2022 soon.

Once your build comes up to start we will contact you to make sure your build schedule is ready and final payment arrangements are in place if a deposit only has been made. Another 25% is due before machining starts. Once the machining starts you can expect about 4 weeks shop time for complete engines and 2-3 for engine kits. When the build is finished and ready for crating we will contact you to go over shipping details and get the final payment.

We accept deposits on engines and engine kits and must be paid in full prior to shipping. To lock in your build and be put on the schedule a 50% deposit is required. Payments can be made throughout the process to reduce the final balance before shipping. All major forms of payments accepted as well as wire transfer and some financing options are available.
Contact us for more details on any of these options or with any questions.
