Hot Rods Small block chevy casting help!

I have a small block chevy casting number 3 14636 and can't find any info. Any help would be greatly appreciated. Mostly interested in what it came out of and if it's a 2 or 4 bolt main. Thanks!

I think you missing a digit I believe it should be this.
3914636
68-73
307
car & Truck 2-bolt

 

Nope not missing a digit. There is an actual space between the 3 and 1.

That space is due to a problem in the mold when the block was cast. The 9 is missing.

 

Ok. Thanks guys! Much appreciated.
