Crankshaft Drilling

Have any of you drilled and tap the crank so you can bolt the ballancer on? I looked but didn't find anything on it.
Thanks!

Watched my father do it on a corvette once with the engine still in the car. You should bring it to a machine shop so the hole is square and true.

I drilled and tapped mine, but if possible, have the machinist do it, as ishiftem said.

I drilled and tapped a 327 right in the car once. I'm not sure how straight I got it but it never gave me any problems.
I can't remember why I did it, I'm guessing that the damper went on a little too easily and I started to worry that it might come loose. :scratch
