Where do I get FCR's for the Raptor at the best prices? Also on a 686 will a edelbrock quicksilver be similar in performance to the FCRs? AND can the stock thumb throttle be made to work with FCRs? I strongly dislike twist throttles.

 

Got mine through Trinity for a lot less than air paid for his. I had all my headwork done there and my jug bored there. I also bought a 102MM PISTON, a cam, gaskets and other stuff. I did not need the airbox adapter nor the filter. Maybe these are the reasons I got them cheaper. Yeah they wont even box the cable up in the same box that the carbs are in, they send it seperatly.

Talk to robertson and see what he'll make a similar manifold for and port match it to your head(or you could do that yourslef).

Reports coming in (Edelbrock on a built bike) say FCR's and the quiksilver are not even in the same ballpark. I know there are those that will argue, im just parroting what I've been told.
