Opinions on Parts Store Crankshafts?

On the bearings you'll likely wanna have the block line bored. And those cranks can come 0.010-30 under while still having the same upc

I've been looking into picking one up from OReilly's. It comes with new bearings too, and it's 50 bucks cheaper than the machine shop quoted me for turning my crankshaft. Are they any good, or cheap chinese junk?

They are not new. They are remanufactured. Who knows what the core will be. I'd be afraid you would end up with somthing that has been welded back together. I've seen it before. Also, who knows what kind of trauma it will suffer in shipping. You have a known good core that is part of a matching rotating assembly. Have it machined.

This post is chock full of sage advice. If I were in your situation**, I would do exactly as suggested here and have your hardware machined. I can certainly appreciate being on a budget, but this seems to be a clear case of where trying to save $50 may end up costing you hundreds of extra dollars down the road.

**: I wanted to be in your situation when I bought my BBC, but my stock crankshaft and one connecting rod were completely destroyed--I was forced to replace them. Had my crank and rod been salvageable, I would have simply had everything machined as recommended above.

Not many shops grind cranks - they send them out and you pay a sur-charge. I would google crankshaft grinding in your area and deal with them directly. I am fortunate and have Crankshaft Craftsmen and Moldex Crankshaft by me that are both well known and in business over 40 years. If it can be ground it's $90.00. Looking at pic's of your crank and bearings I'm going to say its beyond turning and metal needs to be added. O'reillys, Rock Auto, and others are just selling a package from a grinder. Have you ever dealt with Northern Auto out of Sioux City Iowa ?? Been using them for 15 years.

It's not as bad as the pictures make it look, but it's bad either way.

I've seen worse that has been fixed with turning, only time will tell. I project it will be running again by fall time.

you can add weld to a crank and machine it to bring it back to stock size or machine it and chrome it to bring it back to stock size.

I know. I think I'l get by with just a turning, but I'll find out soon enough.

I've been at this for a long time. Even with me doing my own work (Cam bearings, removing-installing rods, heads ) I can tell your going to have bundle of cash in this motor. Maybe you might want to take the same route you did on your trans. Here's an upgrade option and located just north of you.
