The center carb ECG has a SPARK CONTROL VALVE for a LOM DIST.

____________________________

The center carb is the bigger of the three with a 1 1/16 venture.  My distributor uses only centrifugal advance, so I will not be using the vacuum ports. A former owner installed a threaded iron heater hose fitting into the 573.  It's frozen.  I've been down this road before.  To keep from destroying a vintage manifold, I'll be working with my Dremel tool.  I will be disassembling the carbs to see what they need.  I'm sure I will be replacing all three bases.

I spoke with Charlie on the phone yesterday.  He is a busy guy and doesn't have a lot of  time to bench race.  He gave me good advice and answered my questions. He told me to make a list of what I need and call him back. I can tell he doesn't have time for cheap rebuilds.  I see this as a good thing.  I know I'm going to put money into this setup if I want it right.

As far as the hood clearance issue goes, I think the only way to be sure is to remove the hood scoop chrome trim and mount the tri carbs and manifold. I believe I can see the clearance through the hole.  I'm thinking about building a three hole aluminum base and using foam to seal it to the hood like 60s Ram Air.

Good news.  I was able to get the iron heater hose connector out of the manifold without screwing up the manifold. I disassembled the primary carb and it looks like someone put a kit in them recently.  As I suspected the throttle plate screws are buggered up and the shafts are worn.  The screws holding the top on the carb are from a hardware store and are too long.  The manifold is fine.  The linkage is junk.  My list for Charlie is growing.

The next step is to put a vacuum gauge on my engine to check the idle vacuum so I can install the right power valve.   I ordered an intake manifold gasket set.  Hood clearance check after that.

The power valves from Holley are a poor fit for the early carbs (may not seal good).  I believe Charlie has power valves that are modified to fit the early carbs.  You might want to discuss this with him.

Note what Paul said. The modern valves look almost identical and screw right in. And leak. I learned that working on that kind of tri power with 94’s the hard way.

What type of DIST are you using?

I saw the power valve problem on Charlie's videos.  Anyone who wants to mess with these carbs should view them.  I think there are five in all.  I found out yesterday that Charlie produces new Holley 94s. He has a number of options and finish choices.  I am thinking about driving down to see what he has next week. Might be better than messing with three 60 plus year old carbs?

My distributor is a stock 1957 Ford distributor with a Pertronics unit.  The centrifugal advance has been curved and I don't use vacuum advance.  My little 292 runs pretty good for what it is.  The TBird is a fairly light car and the O/D works.  I don't know the exact rear gear ratio, but it's pretty low.
