A really easy thing to do is put on a "stub stack" from K&N or Mr. Gasket. They supposedly help ease the directional change in the incomeing air and add a few CFM to the carb. I've heard they are good for a few top end HP sometimes and cost $30-40. I doubt you would even see it for sure on the dyno, but you wouldn't be risking much $$$ either and its totally reversible.
