340 engine worth?

I have a 340 block crank and heads laying around. I sent the crank out for regrind, it needed it. I am scrounging up other things that I didnt have ,rods, pistons, pushrods, rockers and shafts. A cam, untill all said and done I will have a grand or dern near into it, and that is counting the machine work and scrounging missing parts. I would say if it is a rebuildable core and everything is there from valve covers, intake, to oil pan ,a grand is being conservative. It may be worth more IMO. It depends on who is buying, how much they want a 340. There are those that swear by 273s 318s and 360s etc. 340 is more rare only made 5 years and the first three years are the good ones :)
