M/T Scavenger headers , Need ID help, pic attached
 

Been looking to find out what exactly these are . I kinda think small block vette ,but they seem a little long from top to bottom for a vette. Did anyone else make headers like this other than M/T? There are no munbers on them anywhere and they are definitely old because they have 4 bolt ,round collectors. thanx for any help . DAVE http://images.andale.com/f2/115/106/...er_headers.JPG
