Well, I have about 2 gallons of fuel through my 367 (not modded) and love it. I run the 9901 pipe that came with it and a header off of a JP-2. I am also running the standard C7G plugs like it comes with, and Sidewinder Pro Blend 30/10. It has plently of bottom-in punch with a great mid through top end pull. I have owned several motors (v-spec, P5, 21-5, etc.) and feel that it will run with the best if not out run. It runs any where between 210-230's depending on the temperature outside with NO Flameouts. This is my experience with the 367.
