It would appear to be a 1974- 1980 because the block # comes up as 69-80 on the year range and the heads come up as 74-80. These Heads have a decent valve size (1.94/1.50 76cc Chamber) but are smog style heads and crack easy. Be carefull
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.

That block was used to build 302's, 327's, and 350's from 69-80.
It is an excellent GM block.

350 and 327 [1966 - 1980]
The back of the block will have a series of letters and numbers cast into it. That is what determines the date.
