Thanks for pics. I’m working with Ford style throttle arms which are different than the universal 1850 arms.

Phil isn't using the universal arm, those are dual 660 center squirters.
Cool, but hardly the best choice on the street.

Missed that Drew, thanks.
 I am hopeful to make some rods out of a combo of OEM pieces and some Speedway Motors parts that have been ordered. I would like to avoid drilling a hole in my QF carb, ( rear carb), for an additional trunnion. I may be able to run both rods off one.

There is a this Formula that say so........  ;D;D

The "formula" is strictly designed to reduce customer returns to Holley and/or speed shops.  Has nothing to do with real fuel delivery or engine demand nor does it take into account any specifics of the build it'll be sitting on.  I used to work in parts and nearly 70% of people come in to buy the biggest carb they can imagine for the least likely candidate engine because some bud said this or that, or they read it in some Car Crud or Hot Stuff article.  They have no idea how a carb works, how it meters fuel and lots of time they don't even know what's inside the target motor.  You whip out the formula to try and dodge the obvious fail and the cost of return, restocking, now I have a used $300 carb I can't sell as new, etc.

David Vizard says in his books that if it meters fuel, it's not too big.

I use this for 1:1 instead of the OE linkage.

Yes i know but internet experts always refer to that formula when someone
ask how big carb they need    and ends up that a hot 390 cant handle moore
than a 500 . and that two 600 is way to big at 1200.  and that to big carb drench
the engine with  fuel ;D

  True, but the carbs have had a lot of work before I got them and they do have respectable street manners. BUT it's NOT a car to drive every day between it's high compression, C8AX-D cam and the 4:11 r&p  in the back (being a 3 pedal car probably helps with the drivability) But it IS a fun car to drive. that's why I said "for what it is"
  HTM101, also very nice setup
  Run the Ford linkage to the front carb then make a new linkage to go carb to carb, easy to try and it'll ether work better or not. If not just change it back

Hmmm, very interesting.  Like that - very clean and no monkey business.

LOLOLOL yes.  When I need a carb recommendation, first place I go is Facebook.   :o

Thank you Drew, Phil and Chris.  The simple linkage makes for an overall tight connection.

HTM101, that is a very clean set-up. Very nice and simple.
Couple questions for you; where did you get that bracket and extension that mounts on the carb throttle shaft?
Also, what's the sensor for mounted on the front carbs throttle shaft?

Looks like a TPS are you planning something with that HTM101. I Originally had a 1to 1 setup
but switched to progressive mainly cause I was driving it on the street and it got me a couple of miles per gallon. Hey not that it gets anything spectacular but I don’t really notice any performance falloff.
