I like the guys that want them sonic tested, local cost $175, then want you to sell them the block for $150. There's someone on this forum that expected me to do that for them, nice try!  Had this happen to me recently. 440s are definitely harder to find than they used to be and more expensive now naturally. I try to grab em when I find a decent deal on one, but I have enough stashed away that I can hold out for the cheap ones. Sold all my 383s for dirt cheap and had trouble getting that for them.
