junkyard 440 approx price?

$200 - $300 is fair. I just bought a complete 400 for $200 and brother Dave
(Weeb) just bought a 440 today for a like price. Of course as time goes by
they really will get scarce and the price will rise. If or when they are all gone
you'll have to go with aftermarket blocks but I'll be too old to drive by then!
