I see I have two options...
1. Buy some more Main bearing shells so that I can replace top and bottom that are the same with grooves and single indents. (expensive)
2. Use the bearing caps that came with my 328 crank and the new bearings I have already purchased (no further cost) but will the bearing caps from one engine align with the another?
Going back to the bearing shell supplier is probably a non-starter since they don't list an option for a set with identical top and bottom shells.
Any ideas or other options before I fork out more money on some more shells. |

My understanding of engine building is that the main bearings are line bored with the mains attached to the block, which is why it is important to keep the mains in the same position when rebuilding. I think mixing and matching mains from one engine with a block from another is not good practice and could cause problems later on.
You could try talking to a local engine re-conditioners and ask their advice?
