The DH does not have forged internals. You will not be able to find any reliable source other than repeated forum and FB posts of misinformation. Many shops have torn them down just to find they don't have forged internals.The DH's 5.0 is a little different, both use the same basic 5.0-liter V8 layout, the Dark Horse adds forged connecting rods from the Shelby GT500 and unique camshafts. Would love to have forged internals, but to costly.
