Bow Tie Question

I have never been into Chevys but in my dealings trough the years I have acquired a few things including a '49 Chevy 3100 pick up and a '69 350HP 396 engine. I have decided not to build the '49 and am planing on trading it off. but the 396 from what I understand is an engine of interest to the Bow Tie crowd. My question is do I sell it as a rebuildable engine or would I be better off rebuilding it stock and selling it for a higher price. The block, heads, and intake are all correct '69 350 hp 396. Is this considered a rare engine these days, Is there a big restorer scene in the Chevy world, Would there be a demand for a date correct combo like this? Any thoughts or experience would be appreciated. David
