Looking good Eldo. Impressive considering it just came out of the barn - Herb knows his stuff and there's probably more power and torque with a little more dyno time and fettling.
From your peak HP numbers, it looks like every ten MPH equates to about 740 rpm. That puts the center of the little trough on the left side of the torque curve at about 3,478 rpm.
I would really like to hear about the rest of the build. What gear box are you running? Any streamlining?
