535 supercharged first time start up?

At that level of engine, i'm really surprised you didn't go with a roller. That said, if the carb tune and timing were correct with the 440, i see no reason you cant maintain the 2.5k-3k rpm's needed. I'd run the belt because i could see all kinds of fuel distribution problems with out it. I am curious how the amount of boost at 3k would effect the ring break in. I have no idea, just a thought. Hopefully someone from the "boosted" thread will chime in. Might be a better place for this thread? Good luck with it, it's going to be a beast.
