yup, they are a pretty standard bearing. you can get the same bearing in a bunch of variations, narrowed, doweled, chamfered, x-tra clearance, less clearance, grooved, coated etc...

Here is a Piston rod bearing shot, this is the beat up #8 piston:

Any chance some of our engine builders can weigh in on the bearing condition?

The engine is said to have 40K miles.

Is this typical of what one would see, is the loss of coating were the bearing buts together concerning?

Think I saw Kurt had a sale for mains of around 300 if you need them, only supplier I've heard of for stock or there may be some from Ford or Mopar that can be made to fit.

[LGAFF]

As an FYI, Mahle sent me a follow and advised those part numbers will not work with the LT5.

Jeffvette clarified to me that rod bearings are the same as SBC, but crank bearings are only available through White Racing, and I believe JEffvette might have a few.

Thanks

I used clevite 77 CB-663p for rods. It took extra to get them fitted though cause two rod sets out of the first eight were two tight below limits. They may of worked but out of limits is out of limits even though it wasn't much.
