SRX Air box on a SX?

[cajones2]

I noticed the air box to the SRX is designed differently than the one on my sx. I am wondering that if it would be a good idea to replace my airbox with that of a SRX. I have a Hauck 760 big bore, still running the 31mm carbs on it. I also have the Simmons Hauck Hushers for it as well. Anyway, what do you guys think? I am not sure what the airflow different would be between the two...and would that warrant a jetting tweak?

Thanks,
Craig
