Can someone help me id this crank. Almost looks like its steel and makes a good ring when you tap it. But I'm not to familiar with slant cranks. Heres a pic and part number.
Isn't there a difference in casting/forge seams to tell?
It has a nice ring unlike some cast V8 cranks I have.Looks forged if you tap it with a wood handle of a hammer does it have a "ring" to it or a dull "thud"
Yeah the ring means forged also the "forge" marks are wide and the cast seam is thin and raised. That looks forged to me but the photo is at a distance. I dont see any thin cast marks in it where they would be. More of a wide flat appearance which would also be forged.It has a nice ring unlike some cast V8 cranks I have.
all slants til mid '76 prod had forged cranks.
I think so too, but the point was to get the OP to know how to tell which is why I asked him to zoom the pic. Then I hopefully informed him of what the wider forging marks looked like. I can only hope he understands. I'd post a pic of a cast crank,but right now the only one I have out of an engine is forged.

You can easily tell from the very FIRST picture it's a forged steel crank.
Found this pic on line. I believe top is forged, bottom cast. If that is so (and I've never had a cast slant six crank physically in my hands), they do look different, but not in the way cast vs. forged V8 cranks do. Please correct me if the bottom pic is not a cast slant six crank. The pic came from a Hot Rod article on building a hot slant six, and the cast crank was chosen because it was strong enough and a lot lighter.

Both of those appear forged.
