[QUOTE=Gunslinger]....
A couple of things to keep in mind if changing to an Edelbrock, is you'll have to change the fuel line from the fuel pump to the carb inlet plus you'll need an in-line fuel filter...neither a big deal.  If your car has a/c, you'll also need Edelbrock's proprietary a/c idle kick-up solenoid, which is a bit pricey.  It all adds into the total cost of the conversion.  You'll probably have to get an adapter bracket for the throttle cables (and cruise-control if you have it)...again, not expensive but has to be figured in....
[/QUOTE]

Ok, so it sounds like I need a new intake manifold and I know where I can get a new "Model 2101 SBC Performer Intake manifold" at a good price.  So next is a carb to match. Perhaps the Edelbrock 1406?

However, Gunslingers tips above scare me.  I can certainly remove the old carb and intake no problem. I could likely attach the new intake and carb no problem... its the connecting everything part that has got me worried now.  How/where could I find step-by-step instructions on how to do this?

Thanks guys!

I run a Holley 650 on a Performer 2101. Its a low rise manifold and gives me plenty of hood clearance. I did have to put an adaptor to change the bore. The only problem I ran into was I had to lengthen the choke linkage to reach the stovepipe. It should be no problem hooking up elec. choke. I just haven't gotten around to it yet.  I also had my Quad rebuilt, but I didn't get the performance that I get from the Holley. I don't think it was the carb as much as just not being able to get it dialed in. My feelings are all three carbs are decent. The secret is like Brian says, getting em adjusted right.

Take pics of everything before you start and tag every cable and hose with what they're for.  That way you'll be able to know where each gets hooked up to on a new carburetor/intake combination.  The Edelbrock carburetor manual tells you what port is which, etc.  It's not difficult.  The electric choke on the 1406 needs its hot wire attached to a power source...connect it to a source on the "run" side of the ignition, not a source that's always hot or attached to the "accessory" side of the switch.

The toughest part will probably be the new gas line.  It's easier to access the line from the fuel pump from under the car, unless you simply cut the line and flare it and run rubber fuel line.  Edelbrock also sells a fuel line made specifically for a small block Chevy from the fuel pump to the carb inlet with connections for an in-line fuel filter.  That makes for a very professional looking installation.

None of this is tough...if I did it with my clumsy big hands, you can.  Besides...they're only knuckles...bust one and you have nine more!

I appreciate all this advice.  Now, not to sound completely helpless, but could you point me to all these parts that you are talking about on Edelbrock's (or some vendor's) website?  That way I'd know I'm getting the exact stuff you are talking about.

As mentioned, I'd like to start with the "Model 2101 Performer Intake manifold" as my base.  Since I can get a new one very cheaply.

Thanks!

The Edelbrock number for the fuel feed line is 8126 without a filter and 8131 with a filter.  With these you can simply cut and flare your old fuel line and add flexible fuel line.  Summit Racing may well have equivalent parts under their own name for less, plus they sell the Edelbrock parts as well.

Summit also sells the throttle/cruise control/transmission kickdown cable brackets as well...under their name and Lokar as well.

The Edelbrock a/c idle compensator is part #8059.

Heh wildman, I done saw you change a distributer 15 times in 15 minutes, you can handle this. Do you have a flaring tool?

I was just on the Edelbrock site and they have reconditioned 1406 carbs for $235.95. Saves you some bucks there. http://store.edelbrock.com/9906.aspx

About 6 years ago my QJet was leaking so had to get a new one. Went with Edelbrock and havn't had any problems and it was a unbolt old one and bolt on new one.  Everthing hook up the same as the factory one.  If you have any questions call Edelbrock they are more than  helpful.

Edelbrock doesn't sell their Q-jets anymore.  It's been several years since they dropped them from their catalog and sold off the remaining units at a discount some time ago.  I've heard the tooling was scrapped but I have no confirmation of that.  

All I can guess is the market for new Q-jets wasn't there, or if the tooling was destroyed, that pretty much makes the decision for them to stop listing them.

That's cause I had more experienced men show me how to do it 12 times first.

A no, no flaring tool.
