Thanks.
So I'm at it again. Trying various intakes to see what fits best.
Here is a hogged out Nikki. There are three major problems.
1) I have no air cleaner assembly that fits the carb and under the low hoodline at the same time. I'd have to custom fab something. I figure if I was fabbing a way to get air into the carb, I might as well make a carb hat instead.
2) The throttle is wrapped across the top of the oil filter. The sheath is too short and the cable is too long. This would need a serious redo.
3) The fuel system was set up on the passenger side to work with an Edelbrock and Hitachi. The Nikki and RB Holley have it on the other side. I could get rid of the Holley FPR and swap in a Mallory, also relocate it to be more friendly with the Nikki. But it needs a return line plumbed in, and if I'm digging in that deep, I'd install an MSD pump because it has proven itself in another project recently. Plus they are quieter than the current Carter...
It's all doable, but I'm not out of options just yet.

Here is an RB Holley 600 on a JW manifold meant for an FD engine.
Just test fitting everything here to check for hood clearance. It is a VERY tall manifold. I had a triangular foam "Edelbrock" filter housing that I chopped off 1/2" from the base which still lets the carb's choke mechanism work. I don't dare cut off any more.
The results are almost perfect. Almost.
1) With the hood closed, and pressing down on it, you do feel the air filter. So this could work but is very close. Any engine rocking will make the filter hit the hood. Good thing I've got hockey pucks.
2) The throttle cable is routed around the oil filter, not across it anymore. Using an RB Holley cable bracket bolted to the bottom of the manifold flange, I see a slight misalignment where it connects down at the carb, at RB's two little strips of steel these carbs come with. Probably not an issue.
3) Fuel line routing would need to be addressed.
Otherwise, yes this setup could be made to work quite well! All I'd need is an FD shortblock and some engineering time.

And finally probably my favorite setup so far, and would you believe best fitting?
Camden 5" and an Edelbrock Performer Series 600. Trimmed air filter base, OMP lines routed to the carb, custom throttle cable bracket fabbed from scraps.
1) Throttle cable routes around the oil filter, not across it.
2) Fuel system fits.
3) Plenty of hood clearance. When I press down on it, I couldn't feel the filter. This is like the tallest intake of them all, and it's the lowest. Weird.

Dual DCOEs on an old Rotary Engineering DCD manifold. That's kinda cool. 
Does it drive well? Seems awfully big for the power it makes. But I might be wrong.
Since you brought this to the top, I have an update. I pulled the SC and swapped the Nikki in. I did this because I think I'd like to go turbo, and with all the recent success I've had getting one of these boost prepped Nikkis tuned 100% in the brown car, I see every reason to spread this across every other rotary I can.
All this car needed was:
•A longer throttle cable. I swapped in one with broken clips from a 1st gen. It fits great. Good pedal travel. Replaced the spring with a Hitachi version, good spring tension now. The choke cable seems to work even though it was meant for the original Hitachi 2bbl carb. I'll order a new throttle cable soon.
•Redone fuel system. I just picked up a length of 5/16" hardline and a new fuel filter. Now I just need time to do the work. Just have to engineer a quiet fuel pump mount like I did in the brown car. Then bend the new 5/16" send line to fit and install the Mallory 4309.
•Temporary air filter until a carb hat can be made. Since nothing fits a Nikki I have to fab up something. Probably cobble it together from the base of a stock blue air filter and a foam edelbrock triangle filter. Hmm, I wonder if a stock blue filter would actually fit? Gonna test fit it today if I remember. Too bad RB's spun aluminum doesn't quite fit. Nikkis are very tall carbs with a lot of stuff going on, even stripped down to just the fual rails on top.
