Reply to "Balancing internal or external?"

When the Cleveland was run is NHRA Pro Stock class, way back, the recommended treatment for the stock crankshaft was to nitride it.

I personally have never used the process and it requires someone with a crankpress. The process "warps" the crank and it needs to be pressed back and straightened.

If you could get that all done for free then do it. It would would probable be better to go with an aftermarket steel crankshaft.

The racing rules required a stock crank and block back then. That is why the effort and money was put into it.

The Boss and the CJ crankshafts are not known to be failure prone. The blocks will fail under NASCAR type of abuse eventually.

It's all kind of academic these days anyway and some people can break anything regardless.
