What's the concensus here on Edelbrock carbs? My 14 year old, never rebuilt QuadraJet carb is starting to get weird... Choke'll stay open too much during normal operation (making idle rough and throttle response suck), but sometimes suddenly shut all the way, SHUTTING THE CAR OFF!

The reason I ask about Edelbrock is cuz they make a nice square bore carb at 600cfm that'll mate up nice with the 7101 Performer RPM intake that I want to get. If Edelbrock does make a good carb, as I have heard before, the only question remains is... #1400 or #1406 as far as the 600cfm jobbers go.

LOL Or even more importantly, is there something else you can recommend. Mind you, I'm not looking for complete insanity, here. RoadDemon's not in my budget. I'm thinking AT MOST $300 for a good carb that works nice out of the box and doesn't need to be readjusted constantly or rebuilt within a year.

I have an Edelbrock 1406. I'd have to say it's adequate. Holds its tune pretty well, works well, no major problems with it. The WOT mixture was perfect for my application right out of the box, just had to go 1 step richer on part-throttle. If you're going to go with an Edelbrock, I'd recommend one with an electric choke.

OK, I've got one endorsement. Any more?

Also, what's gonna happen with my computer? I've got an LG4 from 86... Is my carb computer controlled?

So... The question is, between the 1400 and the 1406, which is the better 600cfm electric choke carb for my car? If I get the carb, I'll also be getting the 7101 intake.

Yes, it's computer controlled, and the computer is going to be confused; won't control your distributor properly anymore. You need to replace the distributor with a vacuum/mechanical unit if you go with an Edelbrock or any other non-computer controlled carb (which is anything other than a factory carb).

If I were you, I'd fix the choke problem that you're having with your computer controlled q-jet, especially if it's a daily driver and absolutely if you need to pass emissions testing. Get a Weiand Action + manifold as an improvement; you're looking at a lot less than $300 total. You'll have better overall performance and will keep it legal in case the EPA goons start looking your way.

Edelbrock's carbs are made by Weber. They're pretty similar to the Carter design.

Actually, according to the Edelbrock catalog, they're made by Magneti-Marelli USA, Inc.

Really? That doesn't agree with the big Weber stamp in the side of my carb.

How old is your carb? Maybe Edelbrock recently changed their outsourcing. Or maybe Weber got bought out. LOL Who knows in this crazy world.

Just got it in August, not a rebuild either.

Now that I look too, right on Edelbrock's square-bore carb page it says "Manufactured by Weber USA®, Performer Series square-bore carbs are all-aluminum, ball-burnished and lightweight."

Maybe they don't even know for sure who makes their carbs.

The only difference I can see between the 1400 and the 1406 is that the 1400 is "50-state street legal for all Chevrolet/GMC V8 engines, 1980 and earlier (E.O. #D-215-10)". Given the choice between the two I'd probably pick the 1406.

my carter has a weber stamp on the side too. i have heard that the edelbrock and carters are identical, but don't know for sure. well, cfm options differ between the carters and edelbrocks, but i hear the design is the same.

I have the setup you want and it made a huge difference in performance.
The computer is completely shut off. Car runs great, just doesn't start when it is really cold. It's like 25 degrees outside and it wouldn't start, not sure what it is, never did this before, but then again, it hasn't been this cold since I've put the carb and intake on.
when you do the swap, you need to change the distributor to a vacuum advance unit.

Also, with this setup, I ran a 14.94@91.67mph with a slipping clutch and an LG4 with 133K miles without a rebuild. My slip is here: http://www.leannrimes.cz28.com

Zepher,

I seems that your primary rods are just fine for good weather but they don't taper down enough to provide a really rich mixture for starting in cold temperatures. It's possible for rods to be that lean and cause hard starting, DESPITE the choke!

ECM-controlled Q-Jets are massively rich at the very end of the metering rods. I found that out when I was adjusting the lean-stop or upward travel limit of the rods. I have a post in here somewhere asking for the proper adjustment of that lean/rich stop, whatever it's called.
