Engine decode

[stilwuvme]

I am new here and want to decode this block. Here is what is on the dr. side of the block, 3830930-440-6. Any help is appreciated. Mike

What would tell us more is what is stamped on the pad in front of the valley pan rail on the driver's side of the block and the VIN serial numbers, if any, on a pad above the pan rail on the passenger's side.
