Is there a junkyard gem slant six combo?

I thought so, but don't quote me on it.....this pic looks like both the mains and rods are narrower on the cast....Is this a cast or forged crank?

looking on rockauto, conrod bearings for a cast crank look to be .72" wide, for a forged crank .988" wide
I want to go EFI/turbo eventually. Lighter reciprocating assembly, possibly a lighter block too. The cast crank should handle a turbo. Narrow the rod ends so I don't have to buy K1 rods.
