Not Ranked

I presently have a single holley 850 dbl pumper, 428, in a Unique Motorcar Cobra. It went on a Dyno at a car show this weelkend and only made 288 to the rear wheels at 5300 rpm. I am thinking it is starving for air, it has a 9 inchx 2 3/4 inch air cleaner. I called K+N and they said that filter was only flowing 470 cfm. the reason I am interested in a dual quad setup is two be able to run 2 air cleaners and double my cfm, also, if I have to get rid of the turkey pan which I love the look of, then the dual quads will also replace that WOW factor.
Any help or advice would be appreciated...Thanks, Dave
