They made the windsor and the Cleavland. I always thought the cleavland was the better one ( cause my dad had it in his 1970 Mach 1 mustang) but I have heard other people debate that the windsor is better.
I don't really know the stats on it, but, I think it'* just one of those endless debates that this one is better than that one.
So simple answer, I think it is a good engine. Depends on the shape of it and how hard it was run, but all engines are like that.
