Thanks guys! I realize the tune will change with the motor hooked up and in the car. But,getting a "ballpark" idea on the tune would be beneficial! Cab...not sure if the A/F meter on the dyno is hooked to both collectors,or not! Maybe Raff,or Randy Johnson can answer that. I suppose I SHOULD have mentioned,having the rings broken-in..and finding out right off the bat,if the motor's going to "live" after a couple of 6500-7000 RPM pulls...will definately let me sleep soundly at night!
