We design and build our own Butler custom performance engines.

No matter if you need to update that older GM engine to a new LS motor, want to upgrade your current next gen LS, or build a high horsepower LS race engine, Butler LS is the proven name in performance engines. We can put together a custom designed crate engine from trusted manufacturers. All parts go through the "Butler Process" to ensure it will hold up to what it's designed for.

All engines are balanced, blueprinted, and put on the dyno to ensure the engine is performing to our high standards for power and efficiency.

Butler Performance Services

Need us to go the extra mile and create the engine of your dreams? Our custom engine shop can do just that. We have professional engine builders working day and night to build "Butler Quality" and tested engines for performance street cars, classic cars with restoration engines, muscle cars, and racing engines. Our engines meticulously go through each of the steps in the Butler Process then tested and dynoed to ensure the numbers are as expected. All engines are cleaned and crated, ready for delivery anywhere in the world.

Butler LS and Butler Performance Pontiac builds engines for many projects. Due to the overwhelming popularity of our industry leading performance engines, we take each build in the order it is received. Our engines are meticulously crafted by our professional engine builders, using many of Butler's own processes that have been researched and developed over the years. Obviously we can't build every engine in the world, but we take each project seriously and do not mass produce sub-level quality products.

Because of demand, if our lead time is outside of your projects timeline, we can customize any of our rotating assemblies or engine kits to meet your performance needs. Be assured that every kit we sell is put through the same meticulous "Butler Process" as the engines we build here in-house. Plus we will provide all the needed specs and technical help to you and/or the engine builder of your choice. We work with many top quality engine and machine shops across the country and will be glad to work with yours. Here at Butler our main concern is that you end up with the engine you desire.
