First of all I'm not a machinist, or an engine builder, so here's my ?'s
Do some machine operations or equipment operate from the crankshaft centerline and some from the camshaft centerline?
I've heard there are opinions about if one is better than the other. But then again I'm not sure what I'm asking or if there is such a thing.
Another thing I wonder about when going through and old engine such as ours is, I see some guys use all different kinds of methods to clean the rust and corrosion out of the water jackets. ie, immersion in chemicals, acid, molasses, sonic vibration or newer more hi-tech things. How important is this? I guess I am to anal about it but it seems like it would make a better final product. I also realize one can go overboard on some things too, and it gets down to how much time and money you want to spend.

I think it depends on what is available when you come to clean your block before engine work. Ask your machinist what he recommends.
One thing that is often overlooked is that whilst the block is being machined there is a possibility of rust flakes or even left over core sand to become dislodged. For this reason I have in the past fitted a filter between the thermo housing and top radiator coupling. You will be surprized what it catches. Stops it from blocking the radiator. You have to remember to regularly clean out the filter because it will become clogged otherwise.
For some reason mid-eighties and early nineties cars were renowned as being bad for core sand in Oz.

Here is a link for you in the US for filters like I am using.
