Authentic Custom Engines
At JASPER, we understand the pride and satisfaction that accompanies classic car ownership. Our staff of the JASPER Authentic Custom Drivetrains Division share the same feelings in the quality of their work, making sure that you are satisfied with every detail of this exciting experience.
We offer custom remanufacturing for gas engines, transmissions and differentials. Authentic gas engines include a numbers-matching build, original paint, testing and, upon request and for an additional charge, valuable documentation of the remanufacturing process. With experience dating back to 1942, the latest technology and our passion for perfection, you can expect only the best from a Jasper Authentic Custom drivetrain.
When you request a documentation package, you'll receive bills of material, specifications, dynamometer reports (if appropriate and when you purchase the Dyno Package) and detailed in-process information, including photos. Just about anything you would like to have and know about your engine as it goes through our extensive and precise steps in the JASPER Authentic Custom Drivetrain process is provided. Information is available 24/7 via a web page that is uniquely yours. Details can also be e-mailed to you during our hand-building process. This wealth of reports and photos, specific to your engine build, will be provided to you in hard copy after the final bolt is tightened.
