I have just taken the crank from my LS6 block.

The bearings are slightly marked, but not bad. They have the markings on the underside.
A-400
10 00

Is this a std size bearing, or is it suggesting that the crank has been ground ?

I measure the main journals at 2.555" / 64.9mm

I measure the rod journals at 53.25mm / 2.0965"
both using digital verniers

This was on a parts of an engine I purchased second hand in the UK. I do not have any rod bearings for part numbers either.

I want to buy new bearings, but need to know what to buy.

Thanks, Stevie

Production crank main journals are 2.559 and the rod journals are 2.099. You want standard bearings. I had my crank polished and ended up with .018 clearance on the mains and around .020 to .022 on the rod bearings with standard size bearings.
