I might have some used ones laying around, I will check and measure the width tomorrow morning That would be great. I don't want to go the belt sander route if a shelf solution is available.

Depending on the amount of interference bearing is hitting the radius, the fix could be 30 seconds with a utility knife.

I use Clevite V bearings...Here's the width
changes pics to a BN set getting ready to go in now...notice Tang location. These also Have Dowel holes but can be used with or without.

The narrowed rod bearings have an upper and lower half. If not installed correctly they will contact the radius on the crank. They usually are marked U and L for upper and lower. All 16 Speed Pro shells are stamped with the same p/n, and I can not find any visible difference in the tang locations.

My speed pro catalog makes no mention of the 7135 bearings being narrowed. It does show them as “chamfered”, but the set I have here is not.
I always considered those to be performance bearings for stock cranks.
For cranks with large radius fillets I’ve always used the clevites.
If those aren’t available, then as has been mentioned……what you have can be modded to work.
The Clevite catalog shows the std width bearings as being .912” wide, and the narrow ones .862”.

Two things on that crankshaft, you could have it offset ground down to 2.2 rod journal diameter (BB Chevy size) and increase the stroke to 3,.91 or 3.90 depending on how good your crank shop is and how good your crankshaft is on the indexing of the rod throws, which gives you a lot better selection on rods, rod bearings and use the smaller diameter HD racing wrist pins as well as lightening the pistons and rods up a little. That works fine when you have to bore the block, not so much when you can do bearings and rings to freshen it only, not a new build As far as Clevite rod bearing on the Tri Metal type bearing try using CB529H, CB 527 HN, CB527 HND part numbers I have had to switch in the past to King or Federal Mogul companies like speed Pro or Seal Power due to the warehouses not having the Clevite brand bearings in stock

As Cab said, you need Clevites with "N" (for narrow) in the suffix. The reason I bought my bearing knife 48 years ago is because there would be times like this. Sure it's a hassle, but it's faster than looking for a hard-to-find bearing.
