Class II Engines
JASPER® has been building engines and transmissions since 1942, and in that time we've learned a few things... like, how to get every inch of power out of our performance products. Our Class II performance crate engines are designed to bring your vehicle to the next level.
If your passion lies with street rods, muscle cars, racing, or a project vehicle somewhere in between, JASPER has the crate engine, transmission or a combination of both that will give you the performance you need and fit your budget. We will also build custom applications.
