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.
