Biuld worth-stock/clone vs protouring $$

The `69 I built totally for myself `70`s custom style knowing I would have a limited number of buyers who would like. I was in no big rush to sell but I got lucky and someone really liked the metalflake flames and other custom touches and he swapped in a 440 and did other mods to take it to the next level. This Duster I want to sell fairly quick to fund other projects so I think most guys in the lower price range just want a nice v8 powered street machine they can drive and take to local shows and cruise nights.
