1966 361 block casting # question

[Snowtrooper1966]

Distributor stamp:
B361
3 10
codes out as:
1966 361 w/March 10th production date (and is correct for fender tag car production date of April 1st, IIRC)

But can't seem to get the passenger side block casting number (2658960):

to jive w/MoParts database (or any other Google search):

Know its not a big deal since its not exactly a desireable engine option, just trying to be as informed as possible and keeping good records for the car's history...

Could that be 2658930? Mymopar lists this number as a 1965 361 but didn't see 2658960.

2658930 is a 1965 / 361

The "6" must be a "3" compare the other "6" to the number in question...

Don't think that it's a '65 block, as the distributor stamp and the cast year numbers say 66.
I'll have to get better pix next time I'm underneath....

block still could have been cast in 65...the stamps just mean it was put into service in 66

and the orange paint is wrong for that engine...all were turquoise, no other color

look on the other side of block, there will be a cast date there

Thanks, Bryan.
Do know about the orange paint, and one of the many issues w/shop I paid to recommission the Charger back in November....
Looks like I'm seeing partial cast date (66) above block cast #?
