Fun! 

Well I decided to go for it - 


Went with 42's and a TWM manifold. Still lots to sort out, but Ill start another thread on it somewhere and link it back here. Rought calculations hopefully put it in between an OER setup and a Mikuni PHH setup $wise. 
 

I would probably do them in pairs, then each pair goes to a common shaft.  

Part of running a single shared throttle shaft was for a super clean look- like how datsun_tokyo linked above has it.
I also still haven’t decided on the manifold- but was planning on the TWM one- seems to be the cleanest and allows me to run without all the linkages. 
 
With that said I’m interested- I’ll shoot you PM.

I have common under mount bar mount I could sell you, with either teflon or brass bushings. You would need arms, but it would be the best for actually balancing them. Just a thought.
