Has anyone Drilledand Tapped their crank so they could bolt on the crank pulley? The guys I have helping me are telling me that I should do it. I know it did'nt come that way but what do you think?

If you are talking about one large hole for damper retainer I think you;d be better off to have your machine shop do it.

I'm of the theory: If it ain't broke, don't fix it....Chevrolet never started drilling the cranks for the bolt, until the late '60's.

I did that on my drag engines, of course I was a machinist at the time so doing it in a lathe was no problem. It is not expensive so I would get it done, you might want to put a blower on it some day, good day.

I've never had a problem with the press-on balancer for street use. If you plan on racing or even high revs you should probably do it, if only for peace of mind.

I have seen one where someone polished the crank and the balancer bore so they did not have a hard time pressing the balancer, made a mess. As long as the fit is tight then it should be no issue. If the crank is at the machineshop why not get it done. Good day.
