Can anyone identify this connecting rod number that David is grinding down?

I see it has a bushed end like the free floaters have.

Earlier 318 free floater # 699

1970 free floater #782
(the lightest rod of the 3)

340 free floater rod #645
(heavy rod)

I know the '74 318 had the 645 press fit heavy rod.

________

I was originally thinking it was going to be the 645 press fit heavy rod out of the '72 318 they are building, but then I saw the bushed end.

If they are starting with one of the 2 lighter rods that's a step in the right direction.

What do you think that rod number is?
