g'day
i am new here and i am just wondering if someone could give me some advice about what sort of carb to put on my XF to get some decent power. At the moment the car has WildCat headers into a 2.5inch stainless exhaust with a glasspack. Its got a 4 speed manual. It has a really lumpy CrowCam and the head has been shaved 13mm to up the compression. It has got the standard webber on it at the moment and it is way too sluggish. I have been told to get a 350 holley, a 465 "street avenger", a 500 holley with mech secondaries, a 600 with vacum secondaries or a 650 double pumper. I am not sure which way to go as i am looking for a big kick up the ass. Any suggestions would be appreciated.

Thanks

i've been told anything bigger than 465 is a waste, and those carby matching programs only recommend a 350 for a 7000rpm race 4.1L.
