Best Carb?
What is the best carb for my 460?
I have a 82. I converted it to a 460. Currently I have a stick, but plan on changing to a C6 this spring. I do towing & plowing.
I want good power, decent economy, consistant Idle & easy starting in all weather.
Currently I have a Carter AFB Electric choke Aprox. 600 CFM. It runs well, but the Idle changes from day to day. Fuel economy 8-9 MPG.

Edelbrock or Holley, depending on Personal preference.
Id say 600 is a Wee bit small for a 460....How many RPM's does she see?
Both of the above brands are incredibly easy to tune (although Ive never owned a Holley, I base that statement on reading) so do some research and purchase the one that seems right for you.

The carb you have probably just has some dirt in the idle curcuit. The Carter is very simuliar (sp)? to the Edelbrock and is easy to work on. You can buy a kit for it and take it apart clean it with some carb cleaner and blow it out good with air and should work great. I HAD an edelbrock that I would have to clean the idle circuit on about twice a year. For what you are using the truck for a 600cfm will be fine.

I had a Edelbrock 600 CFM on it originally, but it started misbehaving & I tossed on the AFB. The Idle issue has allways been there, through both engines & both Carbs. The Idle would change by as much as 500 RPM based on weather or the trucks mood or whatever. As a result I have to set my idle very high so that on the days when it wants to idle low it does not stall out. This is wasting fuel and is annoying. Both carbs are quite old & I think it's time for a new one. I just want to get the best one.
Anybody use the Demon carbs? How about Double pumper vs vacuum secondary?

You can buy a new Holley 750 vac. fairly cheap and it will work great right out of the box. I also think you should look for a vac. leak somewhere on the truck,brake booster, heater controls,emisions, ect. Do this before you buy a carb.

A double pumper does not open all of the butterflys at the same time...
They start to open the secondaries after about 1/3 throttle. This is known as progressive linkage. Some dominator carb do open all at once.
A double pumper is not a good choice for a near stock 460 with an auto trans though.
Use a 3310 holley with vac secondarys and you will be fine. A 600 is too small and will kill the peak HP and torque values.
