I'm ready for another mod to my Raptor. I have yet to get into any type of motor work. I would like to call Craycraft one day and get a big bore, but for now what should I do next?

I've been doing my homework on the FCR and Edlebrock carbs? Is FCR worth the $$$.

Can you guys out there give me some pro's vs. cons on carb kits. Keep in mind I want to go with a 690 or so in the future.
