427 Crank Question

Ok is it ruined? Or can it be fixed?
I tried to use a 3 prong puller to remove a cam sprocket. I tried too hard I guess.
The puller broke off inside the crank and may have ruined the threads inside the crank.
I have tried to run a die through and it does not seem to be working. Seemed to work ok then it will not thread a bolt in now.
So here is the question...
Can a crank shaft be filled and re-threaded by a shop?
Or is the answer to cut a new, larger thread through? But if that were the case you would have to enlarge the pulley as well for the larger bolt correct?
What are your thoughts?

Yes. Drill it to the next standard thread, and overdrill the pulley. Easy.

Thanks for the advice that it can be drilled out. But for some reason i ran through the threads again and then actually took a look at the new bolt I had bought. Sure enough I must have dropped or hit that new bolt. Threads were messed up.
Bought a new one today and it worked fine.
So I think I need to look closer before deciding what is wrong:)

Have a great night.

Nothing wrong with good news, glad everything worked out for you!!!!!
