461 cubic inch Pontiac turbo combination from Butler Performance

 Butler Performance is one of a few who specializes in Pontiac engines. We do testing on our own track and work with various companies to design products for better Pontiac performance. We have parts custom made for our assemblies with some available exclusively through Butler Performance. We have an inventory of blocks, cranks, and heads that we will build for you, or you may send us your own core. We are also constantly searching for the most durable products at competitive prices. Not all parts from Butler Performance are listed.

Butler Performance has engine combinations from 350-600+ cubic inches that can be used for street, street-strip, bracket racing, heads-up racing, circle track, truck pulling, marine, and more. Engines may also be designed for the use of a blower, turbo, nitrous, or electronic fuel injection systems. We have rotating assemblies, engine kits (for you to assemble), short blocks, and complete engines that are dyno tested and ready to install.

Listed below are a few of our most popular engine and assembly combinations, but many more are available. Prices listed with short blocks and engines will be less with your cores and other parts you provide to us. We do custom built engines for any application or just to fit your personal taste. Call for a free detailed estimate.

We can build shortblocks or complete engines using
any of these assembly combinations

We have rotating assemblies from 350 to 600+ CI for any application.
If you don't see what you need call for availability.

Our longrod assemblies offer the ultimate in durability and performance!

These assemblies utilize the lightest, strongest pistons and pin design available. We use only the highest quality ROSS Pistons in all of our long rod assemblies, not the cheaper pistons that many retailers sell at a similar price. Our ROSS pistons have the best weight to strength ratio on the market, and use our own proven Butler Performance designs.
Nitrous Safe.

These Butler Performance rotating long rod assemblies come standard with H-beam 4340 forged steel rods from Eagle or SCAT (unless otherwise noted), two of the best names in the business! Bolt upgrades available if needed.
