I got the FCR's from newbonneville, they were $895. ordered WITH OUT manifolds.

Another benefit depending on where you get the FCRs is that they will come with a matched set of intakes.



Neither NB or TP have manifolds for the america and SM. the bonnie manifolds will not work. I recall that fast fred was working on something for the america/ SM's.

my intake manifolds are not quite stock, I removed a fair amount of material while reshaping them to match my head work last winter. I do not believe are an impediment to these carbs at this point.

I should also mention that, these were not a straight bolt on for the SM like they would be for the bonnie. I had to modify the throttle cable housings and make up a carb brace to fit off of the light weight freak. I also made adapters to allow the use of my K&N pods from the CVK's (which are interestingly, 4 mm larger in diameter than the FCR inlets). fussy work but nothing to far out there.
