I just bought a 454  Big Block Chevy motor and I am trying to find out some info on the casting numbers and date codes

Block is stamped Hi per pas 3999289
TO501DWB
13K554948

It's not torn down yet so I don't know if it's a 2 or 4 bolt main, but it does look like it has a factory aluminum intake on it.
Any help would be great thanks.
