Just dynoed exact engine and made 438ft/lbs torque@4400 and 449hp @5900. It has a very flat torque curve and doesn't dip in hp until after 6300 rpm. A 1" open spacer added 12hp to the top but cost just as much or more torque in the lower rpm.[/QUOTE]

Looks like a good combo, just a question about the power curve, I notice that it torques at 4400 rpm top end. Do you have any info on when it starts to make power ? And is the power curve fairly broad ?

Oh yeah that was another question I was going to ask "has anybody figured out how to upload or make a graph to go on the treads ?"
