Due to the nature of High Performance Builds and the many different combinations available, these engines are not warrantied in any way. This is the standard for our Industry. We have over 30 years experience in this industry and can help you design and build an engine that will best suit your needs. We will not be responsible for installation and tuning which are part of every build. Know and trust the shop you have installing your engine. If you need a shop let us know and we can get you to the right facility to handle your build.
