I might be mistaken , but it doesn't appear to have the angled oil filter adapter that an HO would have.
Factory 2-tone with painted roof is unusual on a 67 GP.
Headrest seats , and probably more unseen options.
Very neat car !

Have only had one 67 428 HO engine and it had the open element breather like an HO GTO engine.
