New Carb.

[kihale]

Have a 1964 with a 390 in it and am thinking of replacing the old factory carb with a Holley 600 CFM. I know it wont just bolt right on and be ready to go, so does anybody out there got a list of other stuff I might need rather that me having to figure out what I need one piece at a time??

1. If going with electric choke, you'll need to find a place to hook it up (don't use the wires feeding your ignition as I believe this has been the source of several problems for me).
2. Some extra vacuum line will be useful as the hookups are in slightly different locations.
3. Get some vacuum 'caps' because the carb spacer has several vacuum connectors which will give you too many connectors once you add the Holley.
4. Get a new gasket for under the spacer - the carb comes with one to go between the spacer and the carb, but not between the spacer & the intake manifold.
5. If you have cruise control, you will find that the connector between the carb & the cruise bellows binds on the carb linkage. I just removed the connector for the time being, but will eventually have to grind off the end of a piece of linkage on the Holley to hook it back up.
6. The fuel line connects differently for the Holley. TBird HQ has a new steel line that is supposed to accommodate the Holley, but I could never get it to fit quite right and ended up putting a crimp in the line. I eventually just cut off my original line so that I could fit an inline filter. I have been cautioned by some that (in general) it is a bad idea to use any rubber line between the fuel pump and the carb of a car because if the pump regulator fails, the rubber can burst, dousing you engine with gas. Many feel this would be a less than desirable outcome.
7. There are two lines that connect from your exhaust manifold to the stock carb. These are not needed for the Holley. You can "wiggle" these out of the manifold. Didn't seem to make any audible manifold leaks so I didn't bother to try to fill the holes in any way.
8. The torque specs for the Holley are in inch-pounds so if you want to torque to specs, you'll need an inch-pound torque wrench.

That's all I can think of right now.

Thanks, at least I know what I'm in for now - Kim

If you use the electric choke it has to be on a switched line. I drilled a tiny hole just below my heater box near the fuse panel and hooked into the panel. Don't forget to put a fuse in that line.

Got a 22 cal bullet all ready to use as a fuse - Kim

First let me say Hi, I am new to the group and new to Thunderbirds. I just purchased a 65 a couple of months ago, the previous owner installed a Edelbrock 1406 electronic chock carb while the original was being rebuilt, when I bought the car he was going to install the original back and keep the edelbrock but offered to leave it on for an extra $100.00 (way too cold in northern Virginia at the time to work on a carb in an unheated garage LOL), I have not changed back yet but by looking at the hookup it looks real easy to do it yourself, if needed I can snap some pictures of how the electronic choke is hooked up so you can have a visual reference - should not be that different from a holly.

I replaced the Autolite 4100 on my 66 Landau with a Holley 600 cfm, bolted right up, didn't adjust anything. Electric choke to the hot wire on the heater blower motor on the firewall, cranked first time and still runs very good.
