Same block my Dad and I used in this thread:

It is a great block. Those numbers are an over-the-counter only block which I think is cool. Maybe the right z28 guy or Corvette person would value it higher but my experience has the between $300-$500.
How did you find this one? Do you know what crank or heads it used to have?
