Native1,
Can you go into a little more detail regarding the pleats on the top air filter? Did you say you picked up 9 hp just by adding the pleated top?

I wish more people would provide the kind of data that you are providing; i.e. one specific change resulted in X hp and Y torque on the dyno. I am actually changing my exhaust and moving from a Holley 750 cfm with vacuum secondaries to a 600 cfm double pumper. I will post my dyno results in a day or two on a different thread (look for a thread titled "A little more horsepower").
