It would be best to change the rod/s . Those are lead babbitt as it's not shiny and it's dull like a lead weight. Do yourself a favor and get a replacement set of rods. I wouldn't go back to that rebuilder if he put faulty parts in and then told you after rebuilding it , wouldn't torque up...

The groove needs to be there to supply oil evenly across surface of bearing and crank along with oil wells. Ford did everything for a reason and if it wasn't needed he wouldn't of done so. https://www.jandm-machine.com/rebabbiting.html

Most likely block is cracked in lifter gallery, that you could hear it trickle into the sump. A magnaflux or pressure test would of pointed this out during rebuild. This can be repaired through metal stitching as we have in the example shown.

Since you're going to be taking it apart, it would be a great idea to have it done. that 63 pound flywheel makes a big difference to the engine when it's balanced as a unit with the pressure plate. Seems everyone says the car runs good but truly runs better when they're balanced.

If they're a reputable machine shop and can do balancing, ask them if they have a CWT or Hines, machine . Just need the "flywheel mandrel" to spin pressure plate and flywheel as a unit. As I have shown in the picture. https://www.jandm-machine.com/balancing.html

We would charge with the parts" ARP rod nuts/wrist pin bushings" would be $783 plus tax so in dollars and cents if you want price you can buy the scat rods before the tariff kicks in. We don't sell parts as you can get them from Speedway or Summitracing.

We remove the material from the two ribs on the big end of connecting rod. Typical set of V8 rods are usually within 6 grams as long as they haven't been swapped out. Yes we have a tool prior to honing the wrist pin bushings that forces the bushing tightly against the rod prior to final honing.

You can send them to us. We can rebuild them with new ARP nuts and new wrist pin bushings and even weight match them if you want? https://www.jandm-machine.com/

For the block repair..as others have said you could use an epoxy to fix that. Cylinder head can be metal stitched and then resurfaced. There may be other cracks in the head so you'd have to check. Something that Every model A goes through. https://www.jandm-machine.com/crack_repair.html
