Re: Who has cammed XF carbies?
I wouldn't rate it at 350cfm or anywhere near that, Holley have a 32/36 DGAV knock-off that they rate at 180 cfm, the 34/34 on the crossflow would flow about the same. You can get power with a small carby (HQ racers) but you need lots of head porting, compression (12:1 plus) and a BIG cam. Also Holley rate their 2 barrels at 3" of vacuum!!
If you want an emissions compliant 180fwhp you will need good head porting a mild compression increase and a cam of about 215 deg@050" with as much lift as possible on a 110 LSA installed 2 deg advanced. Induction would be a minimum of a 350 Holley, preferably 465 Holley or EFI. If going EFI you could go 112 to smooth out the idle for your auto(if you have one). This combo would need 3.23 diff gears to work well and/or a mild stall convertor to help you get out of the hole.
