B100s

Got an opportunity to pick up a couple late model b100s. My connection says they are both slant sixxes. Anything in em I can use on my 76 (late 75 by birthday lol) dodge dart. Also slant six.
Not looking for replacement parts per say. More like is there anything I can use to upgrade it. And does anyone need anything off them.
If not I might take em and fix and sell one and scrap the rest. Getting em on the cheap cheap.
