Let me throw some more details.

You would need to have a bar placed in the exact correct position so the crank gear will mesh with the cam gear. The bar's diameter would have to be just undersized enough to account for the peening process that must happen after you pour the babbitt. The babbitt shrinks and must be beat back into the saddles in the block.

You would also have to figure out how to pour the caps.

The you need to make a tool to set the rear flange to place the crank in the proper spot fore/aft and have the proper clearance.

You can then scrap to fit.

Sound like something you can do?

Keep in mind you have to buy a lot of the correct babbitt as you need to have way more in the pot ready to go then you need. As it sits in the pot the metals oxyidize change the ratios making the babbitt change its properties. You combat this by having much more babbitt then you need.

Clearly I have left out A LOT of details.
Sorry it is not easy or cheap to pour your own babbitt. It is way cheaper to pay someone to do it right. Unless you want to go into business.
