Can someone tell me the differences in Clevite 77 bearings. I've found a kit with Michigan Clevite 77 bearings but I cant find anything about them. Are they any good?

Here's a link to the Clevite site:

Good bearings, we use them most of the time.

Monster I guess my main question is which style are they talking about when they say michigan clevite 77? Is there a michigan model or are they just talking about the company?

Scoot, I'll doublecheck myself on this, but if I remember correctly at one time there were "Michigan" name brand bearings and "Clevite 77" name brand bearings. The combination of both names was the result of a merger. Again I'm second guessing myself because I can't remember for sure. Maybe someone else might remember for sure. The first problem I've ever had with a Clevite bearing (in the newer fancy boxes with the NASCAR logo on it) was just only a few days ago. I'm rebuilding a 350 chevy that is cut .010 on the mains. I went to set the crank in the block and it wouldn't go. The amount of clearance allowed for the thrust washer on the crankshaft was not enough. I had to take nearly .010 off the rear of the bearing to clearance the thrust washer. That was the first time I've ever encountered that. The only reason I'm writing this in this post is because I'm wondering if anyone else has had this problem. Don't get alarmed by this Scoot because I've talked to men who have built engines for 40 years that haven't come across this problem with a small block chevy. Anyway, I don't think you'll be disappointed in the Clevite bearings. I know I'm still not.

You guys are correct Michigan Bearings bought out Clevite 77 a few years ago although you may still find some Clevites in original packaging. Also you probably got ahold of a .010 over thrust bearing. In addition to grinding the main journal you can also grind the thrust to clear up lightly galded thrust surfaces. I say lightly because they only make a .010 over thrust area bearing and only for some engines, the small block chevy being one of them. Hope this helps.

I've already installed the crank in the block. What I did to solve the problem was take a little off the thrust bearing to give me the proper clearance I needed. It wasn't hard to do at all. Thanks for the feedback on the bearings!

And Michigan is owned by Federal Mogul If you buy the Federal Mogul race bearing , or the Clevite bearing , you have the same thing .

What about cam bearings I was told by the machine shop not to go with clevite that durabond (I thinks thats the name) are better for racing. Any truth to that.
Steve, anybody?

Either one would work just fine . When you buy a Federal Mogul cam bearing , it's a Durabond , same with the Clevite . Federal Mogul owns everything ! But prices are getting ready to up on many Federal Mogul part's , due to the bankruptcy situation .
