After reading all the comments it reminds me of going to church. We all go to different churches in hope of all ending up at the same place. In other words, we all have our individual ways of accomplishing a certain task, namely having an overhaul last as long or longer than the original engine. We all believe we are doing the best job possible. [ kind of like the preacher does] This is what makes this old USA such a great country, we can all dissagree and still be good friends. GOD BLESS AMERICA.
