The spreadbore looks like a Q-Jet, but it looks funny to me for some reason. Can anyone verify if it is a 401/425 Q-jet? He says 65 but the Q-Jet was '66 only. It is poorly listed and should go way cheap. http://cgi.ebay.com/ebaymotors/65-Buick-Nailhead-4-Barrel-Intake_W0QQcmdZViewItemQQcategoryZ6755QQihZ008QQitemZ180126968539QQrdZ1 Rick
