After talking to Jasper and being invited to go down and inspect their plant, I was very impressed. Yes, they build to specs, but go beyond it also, like graphite head gaskets and chrome plated valves. Also, they will do anything you want for a performance package. Plus, they don't have cores for the SC engines, so they will pick mine up, rebuild it to the specs I want and deliver it (car keeps the numbers matching). Plus, I don't know anyone else that will put a 3 year, 75,000 mile warranty on their engines, plus a total replacement even if it is your fault for the engine failing. And yes, they will pay the labor for replacement if it is their fault. I know they are a little more expensive, but the warranty makes it worth it.
A local engine rebuilder admitted that he doesn't feel comfortable re-building these engines as they do take special knowledge, and if you don't live close enough to the guys that do have the experience and knowledge (Dr. Fred), then I may have to give the guys a chance that have done it for 60 years. Again, the warranty speaks for itself. If anyone has a Jasper re-build, I would like to hear your take on it.
