Okay so we all know, that i was having some issues with my carb... first the choke wouldnt open now its got that gasket leak...
I know that this is a question so often kicked around most people hate it. But I need to learn a few things, bare with me...
My Chrysler has the stock holley 4160... was supposed to be rebuilt already but, perhaps cleaned is a better description... it is automatic choke, and im guessing vaccum operated secondaries?...
Now if I am to replace this...
What is recomended?
First of the whole CFM thing i dont get and i cant seem to find what CFM the 4160 is? whats good CFM for a 440... im guessing bigger like 700 something?
Should I stay with the holley or is there anything you guys would suggest for replacement... Should i pick up a rebuilt or go for something like an eddy or demon...
Everything seems so pricey considering almost nothing is carb operated anymore.
But I'll take whatever advice i get.
As a side note... i seem to remember having a much more pleasing sound from the 74 NY's carb, it seemed much throatier... why would that be?
dazed, confused... and tired of that fuel smell...

John I was surprised when I learned this. I just stumbled on it as a matter of fact. Holley rebuilds their own carbs. Maybe that is a route to go. Can't go too wrong with the manufacturer rebuilding them. I found them on www.summitracing.com They weren't too bad in price considering. . . $200 Bucks
I believe they are 700 or 750 CFM out of the box. (Factory) Not sure, I never owned a 440 with a Holley, they were always Carters. But 700/750 is the best stock range for a 440. Now I do know, in some cases, an 800 will perform better, but they guzzle more gas. Since this is your daily, and you are keeping the car stock, maybe look into a Holley rebuilt.
When you say throaty, I don't know what you mean. . . . Maybe it's just the air filter you are using, or maybe it needs a new one?
So the choke wasn't opening. I recall mentioning the choke pull off and that maybe it was running too rich somewhere. Glad you got that nailed. . . .
I would do that Holley for you, but I have never been too successful with them. Now that I got the F3 Running halfway decent, you need to drive it. Comeonnnnn up! We want to look at that radio too.

If this is your daily driver, ther is a couple of things I would look at. The edelbrock "thunder series" AVS would probably be the best new replacement, with the best milage/drivability, with a Holley street avenger (770cfm) a close second. Both of these are easy replacements, and a nice upgrade from the factory Holley. The only worry with going with a reman Holley, is making sure they rebush the throttle shafts, they don't always do that. If I was spending the money, I would also upgrade to a nice dual plane aluminium intake, the comination of a nice electric choke and the intake makes for a nicer warmup. Drivability is way better with that combo. Be sure to upgrade the fuel line at the same time, and stay with a metal line, it will help it to not vaporlock. The edelbrock you can use a repro carter fuel line, if you go with the Holley, there is a guy in Colorado who nakes a nice line plus a bracket to move the coil, I used these and the were nicely made and weren't expensive. He has an ad in MCG.

Those are excellent suggestions. But in John's defense, he has a limited pocket book and machanical ability. He's a college student. Now after he has his degree, then we can go wild. Heh heh heh I know a few tricks with the big blocks to make them sing. BTW I agree with the bushings. Most rebuilders ignore that.

I do remember the leaner days. If you are looking for a reman, a Holley reman is a good way to go. Out west here, Napa carries a good line of reman carbs. The one thing to look at before you put your money down is the throttle shaft, make sure it's tight (that might be an advantage of a Holley brand rebuild). If at all possible, use the thick baseplate gasket, it does help with keeping the carb cooler.
