283 Crank id issues!

So I have a 283 crank it reads GM-11 3849847 cast number and have searched forums up and down and can't really figure it out so forums say its forged some say cast. the center line points to cast being a thin line but when you hit it with a hammer it rings like a bell I have read on another forum that sometimes cast and forged will make different sounds IDK. Any ideas out there is there anyway for it to be forged with the thin center cast line? is there any other id number that might help I know there's the date code on it but didn't think that would help much I know by the cast number its a 1963-67 crank just at a total loss here any help would be appreciated. thanks guys!
