Hi, so I have my 347 engine home and am slowly getting it back together, they mentioned that I would need a bearing, that goes in the end of the crankshaft, towards the back close to the transmission. Apparently if you get it together without the bearing it will work but will just make noise, I am trying to look up what I need to order, and I don't really know what I am looking for, I will call my shop tomorrow to find out, unless someone on here knows what I'm talking about?
