Once I get my oil pump's hole plugged, I need to do some break in miles. Any advice on how many miles I should put on the engine, and how I should do it?

I was planning on putting on about 500 miles NA, trying to stay below 4K, maybe going up to 6K after 300-400 miles, and then putting on the turbo. However, now that I've finally gotten the car back together, I'm thinking more along the lines of 100 miles. :-)

The engine was rebuilt with 90.5K miles, just the rings that came with the Wisecos. I'm running regular dino oil, but at some point I'll switch back to Mobil 1. Any suggestions on how many miles to go before switching to Mobil 1?

Thanks,
Mark
