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.
