Converter stuck in cranksaft!

Yes, I'm trying to. I can't pull the converter forward at all because it is stuck in the crankshaft! When I take the tranny back out, the converter stays in the crank shaft. I have to twist and turn the converter to get in unstuck again.

I looked up the numbers on the converter and they say it is for a 318. I assume they did that because it has no weights on it, (since to told them it was a neutral balanced engine)
Is it at all possible that the pilot hole in the 360 crank is smaller then a 318 would be?
