A quick trip to Mortec and it says:

3947041....69-70...302/350......"Right angle" casting identifier, 64cc chamber, accessory holes, good HP head
3947041X...69-70...302/350......"Right angle" casting identifier, 64cc chamber, 165cc intake port, accessory holes, good HP head

I woud look at all the engines of these years in the NHRA Blueprint specs to get which hp engine/car combo they are approved for. I know thats not a quick and easy answer, but it will help narrow your search.
