Switching to two carbs
 

I am thinking about switching from my stock aluminum intake manifold and Stromberg 97 to the Edelbrock slingshot with two Edelbrock 94 carbs. My quandary is hooking up my stock gas pedal linkage to the new dual carbs. There is not a throttle ball on the 94, and I would like to retain the original style rods. What have you guys that have done this found works best?

Re: Switching to two carbs
 

The Edelbrock 94's are designed for hooking up the throttle on the driver's side instead of passenger's side. From the pic's I've seen there is no way to hook up on the passenger's side of the carbs unless you remove the lever from an original type carb and put it on the throttle shaft on the pass. side of the Edelbrock 94. Also, the original throttle rod from the cab will probably have to be shortened to be the correct length with two carbs. Same with the choke control rod.

I have the slingshot and here is a pick of what I did. I cut a stock throttle rod by drilling with a drill the same size as the rod and threaded the end to accept nuts. This gave it a curved end so it would ride on the ball smoother. I installed one inside the original end and another on outside. (You can see the one on outside in the picture)
In my opinion this gives it a stock look. You can do the same on the other side of carbs.
i never checked size but these rods can be found on many different vehicles and sizes.

Re: Switching to two carbs
 

This 94 carb has provisions for attaching linkage on passenger or drivers side.

Handthrottle control.

There are a linkage for dual carbs with an adjustable ball on the middle that way you don´t need to cut the original linkage.

Still needs to be on the right side though.

Re: Switching to two carbs
 

so the hand throttle is on the left side, (I didn't know that was what is was for) is it ok to hook both carbs together with linkage on these?
I have 97's and didn't have this problem but I do like to learn the "do's and don'ts". I left my linkage long on left side. I want to experiment with making my own progressive someday.
Could 37 Truck remove his hand throttle and do something similar to what I have done and be ok?

Re: Switching to two carbs
 

The handthrottle shaft is milled in a T shape at the end and not round don´t remember exactly how long the round part is sticking out.
A couple of aftermarket throttleshafts solves the problem but they are usually oversize and the base needs to be reamed.

37,
If you are sold on the Edelbrock 94's the real 94 throttle arm can be fitted to
the Edelbrock throttle shaft, it's not a big deal. With this sort of simple switch you
can now actuate the carbs from the passenger side and tie the carbs together on the
drivers side, this effects the smoothest and most repeatable action. Anyone who builds 94's has an old oil can full of these arms just waiting to be pressed into service.
Nobody asked but if it was my deal I'd get a rebuilt 97 to buddy up with your
current 97. Only my opinion and I certainly respect any and all opinions here on the
Barn .

Use Lokar cable throttle ( http://www.speedwaymotors.com/Lokar-...Kit,22046.html ) & tie into stock throttle pivot on firewall routing cable to driver side hookup. Lokar offers both the end fittings in the 1/4" ball and fittings to fit the E 94's. Use female ball fitting on stock pivot arm and correct fitting to fit theE94 on the driverside.

Re: Switching to two carbs
 

Thanks for all the response, I am looking for the throttle ball linkage part that goes on the passenger side, if anyone has one. Short of that I can go to a linkage on the drivers side, which I would rather not do, or go to Stromberg 97's as Charlie suggested. I would have to go with extended throttle shafts on the 97's, or use a linkage between the carbs with a stock ball joint in the middle. I have the 94's and the one 97 currently.

Re: Switching to two carbs
 

Reading through the original posting of this topic by 37 truck and the various responses I find it interesting that nobody questioned what the purpose of the dual carp setup was.
From my point of view, it is apparent that "37 truck" is a novice to the vintage car game, adding dual carbs to a stock engine will accomplish very little in the way of performance.
Brings to mind my first attempt to improve the performance on my first car, a '38 Chevy, I was 15 and wanted dual exhausts like the big boys had.
Being pretty handy with my hands I fabricated a "Y" adapter out of flex pipe, attached the Y to the stock exhaust pipe behind the muffler, ran two pipes to the rear of the car, attached chrome tips, I was styling.
My father came out to the driveway to see what I was up to with the car jacked up. I told him, he thought I was nuts, telling me that my "dual exhaust" was not going to accomplish anything, just waste money and time.
Of course we got into a big discussion about the pro's con's of dual exhaust.. As usual he was right, I was wrong..

Re: Switching to two carbs
 

I guess I should come clean, The engine is a 1940 with bore 20 thou over a 239, a max 1 cam, egge pistons, edelbrock block letter heads, reds headers, and a t-5. Not stock, but how I want it. My first vehicle was a 1937 Chev pickup 50 years ago, so not entirely new to vintage vehicles.

Re: Switching to two carbs
 

Nothin wrong with that.

Re: Switching to two carbs
 

I second the opinion on buying a second 97, match the jet sizing between the two and have fun!

Re: Switching to two carbs
 

37,
OK, another look..........97s will not require extended shafts. Removing the
hand throttle arms and retaining caps will provide more than adequate drivers side
shaft length to install generic hot rod carb arms. Tie the carbs together on the
drivers side, actuate them on the passenger side from the rear carb. What's nice
about the Stromberg carbs is ,with your motor, stock jets and power valves will get
you somewhere in ball park.
94's when used in multiple carb setups require massaging, Using Edelbrocks
94's additionally require ,as we now know, removing the 'arm' on the pass side and
installing a genuine Ford throttle arm. I can certainly mail you the arm no sweat. The
rub here is the gennie Ford arm is not going to jump on the throttle shaft.

Use two 97s They will work better for you . Jet them with 43 mains and 67 power valves.

Re: Switching to two carbs
 

Thanks for the help, I had the one 97 rebuilt, think I will get another.

As original appearance would be lost with dual carbs, consider installing an intake manifold with one four barrel carb. We have done that many times at our shop. It provides good idling and low speed driving with plenty of reserve to meet higher demand when the back barrels come on. Sure beats the endless fiddling with multiple carbs.
