Adapter between an Edelbrock 2101 and 1406?

[mrein3]

I have been collecting parts all year for my 383 project.
I purchased a new in the box Edelbrock 1406 carburetor this spring. This week I purchased a new Edelbrock 2101 intake manifold. The counter guy insisted that I need an Edelbrock 2732 adapter to bolt the carb to the manifold. I didn't want to doubt him because I didn't know...
...and it was less than $10.

Do I need this adapter?

The description on the carb box states:
"Square-bore Adapter Plate for Spread-Bore Manifolds - #2732
For installing Edelbrock carbs on some Performer manifolds for GM applications."

I think I don't need this adapter. Especially when I set the new carb on the new intake.

For you folks that are running this combo do you have an adapter in between your carb and manifold?

While I'm at it how does the solid throttle linkage (not cable) work? Any gotchas there?

I really can't help sorry. i have the 1406 with the RPM Air Gap manifold. there is no spacer on mine.

[Harold Shepard]

I think that with that set up the carb you have is a square bore and the manifold is set up for a spreadbore- q-jet type carb. The spacer prevents the vacumn leak that will occur from happening, so check to be sure on the carb but I think you will need the spacer.

Edelbrock # 9266 , is said to seal the edlebrock square bore carbs to perf. perf rpm, & airgap manifolds. For the square bore holleys, on the spreadbore intake, you will need that 2732 adaptor. I think the base of the edlebrock is just a tad wider on the sides, to let it seal. good luck,crazyL

I have the exact same setup as jorgensensc and the only adapter I needed was for the top of the carb for the air filter to clear the carb. Doug

the so called "ADAPTER" is simply a thin metal plate to insure a good seal between the carb and manifold back by the secondary`s where it is thin along the outer edge.edelbrock recommends this only to avoid any problems,and i would run it to avoid any.

On the linkage. Just picked up a "throttle rod shoulder stud" Edelbrock part #9141 from a local speed shop. The hole for the rod is a bit small (I'm not sure if my linkage is original), but it can easily be drilled or tapped.

Heres a link, look at the very bottom row in the pictures second from left I think: http://www.edelbrock.com/automotive/install2.html

Harold Sheppard said it well. I always run them when using square bore carbs on the Performer intake. It removes a potential vacuum leak.

Thanks everybody.
I guess the parts guy was right. I'll install that 2732 adaptor under my carb.
And thanks BtnkBndt for the throttle rod shoulder stud tip. I like having everything available BEFORE I start putting stuff together. That stud is under $10 too.
I just hope I can get my aftermarket cruise control to work with this setup.

my experience with edelbrock carbs is that they like that heat insulator gasket, to prevnt fuel perculation. Not to be arguementative...but the info i gave came right off the edelbrock site! Ill try to link it.... http://www.edelbrock.com/automotive/index.html go to carbs, then carb accessories, & you will find the info on the 9266 gasket.....crazyL

Crazy,
I don't think anybody thinks you are being arguementative. I'm looking for the BEST solution. I remember folks here talking about an insulator type spacer under Edelbrock carbs.
That 9266 part number is less than $20 at summit on-line.

I anybody out there running a 1406 on a 2101 intake with this 9266 heat insulator gasket in-between?

[Tx Firefighter]

Actually, Crazy is on to something. The Edlebeock/ Carter carb are sometimes hard to start on hot days. After you shut it off, the heat from the engine will boil the fuel out of the carb, and next time you go to start it, you'll have to crank it for several seconds to refill the fuel bowl with gas.

An insulator will alleviate this issue.

Matt, you WILL want the heat insulator gasket too or instead of the other one. I have the 1406 on the 2101 with just the insulator. Without it, the carb would sound like a kettle at full boil on the stove. Something about gasoline boiling that makes me uneasy.

[crazy longhorn]

That 1407 on my 383, was really bad about "heat soak".....the thing would not idle right when it got hot, & hard to start after a 10 min run into the grocery store! I thought holleys were bad about percin the fuel, till I played with that edelbrock! all in all, after dealing with float level problem(bounced too hard in shipping), & getting the fuel pressure where it should be, & a little minor jet changes,& the insulator gasket that Edelbrock works pretty d@mn good ONE THING I HATE THO... even with my bi-focals on, I cant read the # stamped on the rods &jets Oh well, i guess thats what the dial caliper is for.... crazyL

[mrein3]

Thanks everybody for the tips.
I'll be ordering the 9266 fiber insulator/gasket and the 9141 throttle rod shoulder stud.
This board is the best!
