ANOTHER Crank ID Fordged 318 stroke

I scored this for 150 shipped. This is the crank I though was a eight bolt flange, but its a six with I guess some balancing hole or flexplate lineup hole.
It has 15435 stamped on the front most counter weight, on the surface that would be closest to, up against the front of the block, directly besides the number one main journal. I dont have my mic to check the journals, but the guy said it was 10 under all around and had been magnafluxed. It also had a yellow magnaflux tag on the crank throw stating it was OK, for whatever thats worth. Looks like a good crank though.

Here are some pictures.





I can take some more, but I will have to wait a day or so to measure anything.

Thanks for any help
