I know this isn't much of a concern for some looking for all out power, but is there a way to test fuel consumption?
Based on a stock head vs a lumped head, etc. Say, x-amount of fuel and record how long the motor will run on it? Giving us a comparitive look at how headwork can effect all aspects of an engine?
Just a random idea that might be fun to play with, since it's a controlled test environment. ALthough it might not be very cost effective.
