Out of mere curiosity I read jaguars article on Wikipedia the other day.

http://en.wikipedia.org/wiki/Jaguar_Cars

There it lists three historical Jaguar engines, one of them being the AJ6. I then of course read the article on the AJ6. For some reason my curiosity was not satisfied. What makes it historical?

I would really like to see the input on people that know of worked on such an engine. If I remember correctly, cadillac once referred to this engine as bulletproof. That sparks my interest. I agree, but only for the mere fact that mine has been extremely reliable. At 210K + miles, it runs like a champ. My problems have always been mainly cosmetic, or routine maintenance, never the engine. Other than that, I don't exactly know why it's such a great engine

 

in their context it is historical in that they no longer make them. from my viewpoint they are historical because of the engine they replaced, which powered jags for 40 years...
