Why do you think you spun a bearing? Not running as well? Are you sure it isn't something else?

If it is a spun bearing, you will most likely wipe your crank also. You will have to yank your engine, pull your crank out and get the crank ground, then get new bearings.....basically you should just do a rebuild on the lower. A stock rebuild can be had for less then $1000 if you buy cheaper parts and shop around the machine work, but that all depends on you plan for the car for how cheap you want to go.

might as well pull the motor, if the bearing spun in the cap, rod will need to be resized

If your bottom end is toast now is the time for a stroker, it can be bought about as cheap as a stock rebuild.
