The bottom ends of these engines really don't have a lot of issues other than spinning bearings for no reason whatsoever. So, I doubt you would have a ring issue. Oil ports getting gummed up could happen, but I believe it would take a serious amount of neglect to get to that point. So, you're narrowing it down slowly, which is good. I know you had plans for the vehicle. You might want to write them down and start asking good questions and doing a lot of research. My build was done with basically a tried and true setup...in other words, my engine is bulletproof. However, the trans has issues that I was unaware of and am searching for a replacement. It's best to make a list of what you want, what your goals are, and go from there. The forum is not always the best place to start throwing new ideas around, but there are a bunch of us here who like new ideas and if you can find the others, then you have a great group to bounce ideas off of and have a really nice build.
