I still have my original pistons from my body off. if I remember correctly they are made byTRW. My engine had very little wear after forty years.
My rebuilder was going to go 20 over instead of the more common 30 over but couldn't find pistons that we wanted in 20 over so we went with the larger bore. I would think the bore has some wear, Is the GM part number that was posted for a larger piston?

Speed Pro #L2340F30 Summit or Jegs. I used them for my 1970 L46 rebuild. Make sure they don't remove the numbers from your block. If you care about preserving the original numbers. Have you decided on the compression you want. The L46 cam has a late closing intake valve.

I think you mean L2304 pistons, not the L2340...
