Found a 440 Motor

I'm still on the fence. I think $400 may be a little much. It's a friend of my dad's that has it. He told my dad that he might sell it or he might not.
I have a good 360 sitting in the garage now. I think I could invest that $400 toward a set of 340 heads and make close to the same power as the big block. My block is already rebuilt, but with stock parts.
From the way I write this, I think I'm leaning toward passing on the 440.
