I was wondering how many miles you big bore guys have put on your engines after the mod. . It's fairly well documented that you can get 100,000 miles plus out of the engine in stock form. I have been contemplating doing the big bore kit but I don't want to shorten the engines life span or it's reliability. In my experience with muscle cars and Harleys, it seems when you bore out the engine etc. the reliability goes way down.
