Good reply Hotrod.....GM wanted this thing to move 4000 pound cars at low RPM. They knew it would last for a longer period of time than they needed to worry about. We, on the other hand, Have found ways to mess it up and it is up to us to make our demise a bit better than we hoped for. My rant was for the fact that somebody fell asleep in class and woke up at the wrong part of the lesson and now wants us to believe that mysterious things happen inside of an engine. I'm sorry, I can't let pandora's box be opened more then it has already. I mean no harm. Maybe we need a thread designed by the mods for instruction only. I know it would put most to sleep, but those who wish to learn will put it to use. And yes, if your budget or availability of parts lets you get by with the combo, by all means run it. If you ask questions, you want to learn or you would just slap it together and scratch your head (not you, those in general).
