a/t kickdown
How does kickdown tie to carb?
I recently bought a 69 f-250 ranger camper special with 390 2bbl carb. The kickdown rod from tran is just sitting up by the carb, not connected to anything. I'm going to install 4-bbl edlebrock and am looking to find out how this rod originally attached and if it needs to be changed.

Rich, presuming you are going to purchase the 1406 600 cfm carb for your truck, you will need to buy the attachment to use the kickdown.
Sounds like the carb has been changed out.

In the still cool hours of the night, you can hear chevys rusting away.

if you are going to switch to an Edelbrock or other 4v you will have to lengthen the rod somehow. I had two laying around so I cut a piece out of one and welded them together.
The idea is to adjust the kickdown linkage to where it moves back when you have your foot fairly into it. I set mine to kick down when the secondaries open (higher rpm=more vaccuum=better carburetion with everything open).
Once you get the carb and adapter, it should be pretty self-explanatory. You also may have to do some fabrication with your throttle linkage because the Edelbrock carb is quite a bit wider than the stock carb. Also, the four barrel will sit farther enough forward on your engine that your throttle linkage may have a bit longer stretch to the carb than before. This is something that you do not want to "make fit" because it may lead to stuck throttles--not sure, but this happened to the guy I bought my '67 LTD (390 4v) from.
