if you spun a bearing most likely you have debris everywhere in your engine. What you are attempting will most likely cause another debris induced failure. I would recommend getting the clock hot tanked and cleaned including the oil galleries. Run a light hone and re ring all pistons, change all the bearings, replace said rod with a good one, replace crank with a good used one. make sure you get it polished. use a new oil pickup, ensure your oil pump has been cleaned and has no scoring. Make sure you get the heads washed out and replace valve seals as a good safety measure.
