Just finished the initial break in. I've run about 6 complete tanks through the car so far. It was a nightmare to start the first time. The pinch was killing my starter box. Once I finally got it to turn over, I found that the factory needle settings were way too fat. It flooded the engine almost immediately. Once I got the needles right it fired up and ran smooth. Last run for break in I leaned it a little and ran it around the yard. It was still rich and spitting oil. Temps hit 217 and I got 9 minutes out of a little less than a full tank.
I'm headed to the track in a few and will update again afterwards.
