Another 308 casting number ID question

I have a rebuilt 308 with the following casting number
16D4
The engine number is no longer visible I assume as the block has been decked.
Can anyone make sense of the number? I have read the various lists etc but couldn’t find the 16 prefix.
Thanks Richard
And 308 cast onto side of the block.

D is the 4th month of the year.
4 is the year.

Or 94? Commodores didn't get LS engines until June 1999.
Usually the engine number sequence is enough to figure out which decade it is, but without that we would need to see a LOT more detail from the block including the capacity casting(s) on the side(s) (one side or both?), bolt patterns (bell housing, cylinder heads), pics of the cast webbing around the rear main seal, pictures from inside the crankcase and so on.
Do you have a receipt with the original engine number on it? Or an old set of rego papers?

I would assume '74. Mine reads B I 82. went into a VH back in '84. I'm guessing 09/82. Don't know what the B is. But it's definitely not an 8.

"B182" will be the 18th of February 1972 and will have a neoprene rear main seal.
The numbering system for cast dates changed around the end of 1972 from the "month-day-year" (American format) to the "day-month-year" (Australian format).
If your cast date is "B182" then it definitely ain't a Commodore engine and if the engine number stamping says it is then I'd be worried!

Cheers, yes it has the neo rear seal. Also has HQ big valve pre smog heads, so I think you are on the money. The 1 is an I. Engine # has been decked off and all that is visible is T1.

It would have been QT.
