702 Twin Six

I thought I knew all GM gas engines till I saw this gem! Installed in a cabover from the factory. It sure looks like its roots were in the same place as the 348's,the heads appear the same,but it almost looks like 2 348's without an opposing bank of cylinders machined together! Its about 6 feet long as well. Any info from those more informed is welcome!
Thanks
