333882 is the identifying number for that head. If you combine with Block, Manifold and Exhaust castings, you will find out from which vehicle your engine came.
This does not appear to be a question.
It's probably a 1972 350.
and it has aluminum hi rise 8 inch ballencer painted orange
That block was used to build 302's, 327's, and 350's from 69-80.
It is an excellent GM block.
casting number 3970010 is a 350 block from 1969 - 1979 but in 1969 302 and 327 have the same casting # and im not to sure about the other #
Numbers on the motor of trucks and other vehicles are identification numbers for the engine block casting. These numbers identify the batch of production the engine block comes from and can be used in recalls.
GM engine block # 3970010 was used as early as 1968 on some 327ci engines. From 1969-1979 it was a 350ci engine. It could be a 2 or 4 bolt block used in cars, trucks and even corvettes. You can also find these blocks with a "MEXICO" stamp on them near the block ID. It has been said that these are high nickle content blocks and may be stronger than others.
The back of the block will have a series of letters and numbers cast into it. That is what determines the date.
350 and 327 [1966 - 1980]
