Dan,
I know your trying to do your car as cheeply as possible... but really, the bottom end of your motor is the one part where scrimping will only hurt ya in the long run. My recomendation, is take the block to a machine shop and have them go over it, and make sure everything is ok. They can replace the bearings, and if anything is out of spec, they can correct it for ya, and make sure that everything is spot-on perfect for ya.
