I know NOTHING about the engine.

Here's all the numbers I can find on the block.

010
J257
40GM
3970010
12B N (??)

It has aluminum heads. Any idea who they are made by? I can't find any markings on them, other than a cast in capital "A" with a circle around it, and the number 0895.

Here's some pics:

just a garden varity 2 bolt 350 used from 69-80; not sure which numbers you found where but guessing the casting date is oct 25 1977. are you sure the 0895 on the heads is not a 9895 which matches up to a 2000 and up 5.3L vortec engine.
