Well I found this in my shed



Fomoco Low Life

I also found these kick down rods. How do I know which is the right one?


Fomoco Low Life

The top rod is a SHIFT linkage rod.

The middle rod is a kickdown rod but it has no bracket for the clevis pin attachment.

The 3rd rod at the bottom is the correct rod for a 55/56 ford. In 1957, Ford changed the style of clevis attachment where the pin would go through a "fork" shaped bracket that was on the threaded rod. This correct rod in the photo should attach to the end of your bellcrank in the photo and a cotter pin can be used to keep the bracket in place on the bellcrank.

EDIT:

Once you get it hooked up, there is a simple "baseline" procedure from the Fomoco 55 or 56 Ford manual. Basically it involves lining up the two holes on the driver's side of your pictured bracket, placing a pin in those holes, and then putting the bracket on the top of the kickdown road in a particular distance on the rod. Hook it up, drive the car, and then adjust up or down as needed for your transmission to drop in the lower gear on demand of the accelerator pedal.

So you are saying if I want to run all the factory fordo brackets and what not with a 3x2 I have to use this style linkage?( The one pictured on top of the cruiser skirts) Is this the bellcrank or does this mount on the firewall?

The bellcrank mounts to the intake. The Edelbrock 553 manifold (designed for '55-56) has the bosses for it.


The 573 manifold (designed for '57 up) does not.

See that's the problem. I am not running a 272 and that's what the 553 is for, they have small ports. In running a 292 with the big ports which call for the 573

Fomoco Low Life

Not sure that's a problem... I'm running a port matched 553 on my 318" with 'G' heads and I believe Tim's '30 has a 553.

I have done some research and have been told that the ports are smaller

Fomoco Low Life

Yes they are. Here is a Dyno test comparison that Ted did a while ago (Thanks Ted). As you can see the 573 made ~9 more hp than the 553. Which places it in 2nd place with all the 3x2 manifolds.

If you are looking for MAX hp your going in the wrong direction. Get a Mummert 4 barrel manifold with your choice of Holley or Edelbrock carb...
