How much power did Steve predict for the four-barrel ARDUN before the dyno?

Peak horsepower somewhere between 5,500 and 6,000 RPM, and somewhere between 300 and 315 horsepower. Barry repeats it back as 5,500 to 6,000 and 300 to about 315 or 320. Steve says that if they see something certainly lower, he will be looking for what is wrong with the engine.
