Vintage Mopar 28 blocks and 60 cylinder heads plus more!

My uncle was a machinist in Portland OR and when he passed he left behind a massive collection of vintage Mopar parts including 28 blocks and 60 cylinder heads plus much more. Everything is categorized by casting numbers, date codes etc. Anyone know where to go about selling something like this? I want to help his wife get the most money she can for this stuff but don't know where to turn and thought I'd start here. Not really looking to sell stuff individually yet but perhaps someday we may have to. Thanks in advance for any help.
