Hello
Update
This engine is stuck bad. There is powder antifreeze when I took off lower radiator hose. I try to get engine loose and use Marvel oil treatment see what happens. I have a feel this engine is toast. Any other ideas???
I decoded the block it’s a 3970100 block all the pulleys are from mid 70’s truck. I think this engine probably came out of a mid 70’s truck. It’s set up like that in engine bay.
