I'd be interested in how much he wants for it.
You can always make an offer.
Denny Graham has a full set of (12) GM NOS
solid lifters GM # 3836342 that you might be able
to get him to sell to you. I know they are in mint
condition.
Here's a photo of the lifters Denny has.

What's the part # of the GM NOS oil pump that
you'll probably want ? I'll see what I can find.
I'm not 100% sure on this part #...but it might be
correct. GM NOS oil pump on ebay.
