6 cyl chevy block ID

That looks like a VIN number to me, but we'll get this figured out yet! The chart that others keep posting doesn't cover the later '62 and up blocks.

Tell me, is the fuel pump mount in front of or behind the distributor?

I'm assuming you have only the block and not the head? Because the valve cover and head healp a lot in ID'ing these.

The CONXX is simply the conveyor number the mold was carried by. It tells you nothing useful.

Do you know if it will bolt to a 'normal' GM trans, 60's-90's? That limits the selection.

40's engines use a single side lifter cover on the right side that goes all the way to the head. 50's/early 60's use a single cover that stops well below the head. The 'late' L6's (1963-90's) use 2 side lifter covers that are rectangular and stop well below the head. Eahc covers the lifters for 3 cylinders.
Assuming you have a 'late' block, the 194/230/250's have the fuel pump in front of behind the motor mount, the 292's hav it behind the motor mount (usually a triangular rib pattern on the block with 3 holes at the corner). Side covers for a 292 are ~6" tall while the others are in the 4" range.

194's have smaller bores, 230 and 250's are the same bores (3 7/8"). 194 and 230 share strokes, 250 is more. 292's have 250 bore but much more stroke. Rotating parts don't swap between 292 and others.

Hope that helps.
