That would be a fairly 'correct' 71 400 for you (YS would have been from an automatic car, but regardless), $1400 is too high for a core short block, IMO.
If it was a complete engine, especially with the #96 heads, then I would say you might have something.
Personally, I would pass on this one too.
But since you have a lot of other things to do on the car, keep at it. The right engine will pop up. Keep an eye on the classified's here on the forums too. Someone up in your neck of the woods may have just what you need.
