Hot Rods SBC Identification Help Needed.

Looking for help identifying what year, displacement, horsepower of an engine. Stamped on the block in front of the passenger side cylinder head are the following:

V1006ZDD: I've found that "V" means Flint MI, 10 is Oct and 06 is the day of the month it was cast. I need help identifying what ZDD means. Possibly 1980 Corvette?

1BS405857: is stamped below the above number, no clue what this means.

Thanks for any help you could provide.

 

"ZDD" - 1981 350, 190 HP, manual trans, 4 barrel, Corvette.

 

I get the same as Ericnova.

1BS405857 is a partial VIN for the original vehicle.

 

1BS means 1981 car built in St Louis...which is where they built Vettes through 1982.

Damn, a small block chevy motor that is actually out of a vette! Almost the lowest performance one, at that

 

Thanks to all, I appreciate the help.
