Try this routing with an 84.5" belt assuming your pullies are stock



Consequences would be potential damage to the cats due to incomplete burn of any hydrocarbons that are left from the combustion process. Given that you are driving 1000 miles, i assume you are doing highway miles, so your cats should get nice and hot so this really shouldn't be too much of an issue if the vehicle isn't running overly rich. Just get the pump functional as soon as you can.

If you have an off-road H-pipe, no consequences at all.

I drove my car for several years (prob 1-2K miles) without the smog pump hooked up with factory cats. I late rehooked the pump up. As far as I could tell no damage was done to them.
