Raised 1957 325 (also fits 1956 315) D500 Offenhauser Dual Quad Hemi Intake Manifold I bought this a few months back without doing much due diligence and just listed it on an auction site. Needless to say I was offered about half what I paid. Question: What is this truly worth? I paid $400 and was offered $225.. Is this a case of another expensive lesson or is it worth close to what I paid? Thanks guys
