I love my Systemax intake, yes the runners and ports are huge and do not really match up with any head with out a little port matching but I have had great results with the combo on my 302ci motor, it should go mid 11's with the 4:30's that will match my cam. So far I have went 12.16 @ 113.5 on street tires, I just got a new set of 26" x 11.5" ET STREETS and I am heading back to the track on Saturday hopefully for a 11 sec pass. I say buy the Holley and never buy another intake again.
