Any crank, new or used, needs to be checked before installing. That has already been done on the crank in the kits, as well as other parts.

Just like the bore, even new cranks may need to be turned to make them 'true'. That's already done in the kits.

So the money to prep the crank you have is a saving.

You 'can' stick with the OE pan, but it doesn't provide very good oil control. Not to mention used pans can be dented, tweaked, or whatever, and not fit or leak.

Also, new pans usually have a pickup that is properly size, reduced restrictions, and most have a bar on the bottom to prevent from being too close to the floor of the pan.

It's possible to also have an incident that causes the pan to be dented, making the floor of the pan too close to the pickup, restricting flow.

Aftermarket pickups usually have a retaining strap too, so you don't have to weld the pickup to the pump.

Welding the pickup to the pump in my opinion can compromise the pump body.

As for the comment on bore size by Butler's site, this is what I was talking about when I mentioned 'squaring' up the block. Even if you could use the existing bore, the factory tolerances are not as good as an aftermarket block prep, and usually improves the relationship of the bore centerlines with the crank centerline.
