Thank you for selecting Karl Performance Parts as your GM Performance Parts dealer and welcome to the Engine Builder and Dyno portion of our site.

Here you can build, dress and Dyno test your own crate engine, just dress your own crate engine, and if you prefer to see how a stock crate engine straight from the factory will perform, you can Dyno test that as well.

As you build and dress your crate engine, we encourage you to write down the part numbers you are using to build your engine to your specifications.   After you have built and tested your engine to achieve optimum performance, please proceed into the Karl Performance Parts website to search the parts used to build your engine just the way you want it.  For easy navigation, please enter the part numbers in the search navigation window to narrow down your process.

If at any time you have any questions, please give us a call. We are here to help.
