Default Ganging of VIN on engine stamp

I'm dealing with a non-Corvette 427/390, but since all of the L36 experts are Corvette owners, I'll check here. This is actually out of a 1969 Pontiac 2+2.

I'd like to get some input on the ganging of the digits (which is poor) and the broach marks (which look OK to me).

There's pretty much ZERO chance someone would take a 3963512 block and clone it INTO a Pontiac... it'd become a COPO or LS-6 I'm sure. But it's an educational step!

This should decode to roughly "1969 Impala SS 427/390" and it does. But because this is actually a Pontiac in the Oshawa plant, not a lot of 427s were used. In fact my car is the only four speed ragtop and there were 12 four speed coupes. Total! So it wouldn't even surprise me if they free-handed it on big blocks in the Oshawa plant.
