The 6pack fits under both the flat hood and bulge hood in 70 , it fit under the stock hood on a 68/69 Road runner, I'm pretty sure I've seen them under the Ramcharger hood on a 69 Bee/R/T which is a flat hood so I'm 99% it will fit under the bulge of a 68/69.

BUT that said you need to confirm it before closing the hood.

I just put a Six Pack on my Bee and used the above air cleaner with a K&N filter. Easily fits under a '70 power bulge hood. The air cleaner studs supplied with the kit sucked so I got better ones from Mega Parts:

Is the throttle cable the same just a different mounting bracket on the intake?

I reused my 4 Barrel cable and it seems to work fine. Yeah its a different bracket needed. I bought an installation kit from an eBay seller that had everything needed to install except the idle solenoid and bolts( cabs,manifold ,and solenoid). The kit came with a new throttle cable but haven't installed it yet.
I had already installed new 3/8 and 1/4 steel fuel lines / gas tank sender, and stock vapor separator so only used the upper lines that came with the kit.
The best part of the swap is giving away the Edelbrock 1405 and 1411 that had been nothing but a huge pain in the a$$. Good riddance!

How quickly this got on a "crap gasoline" bashing thread. Facts are often left by the wayside.

Here are some facts:

In metric units from Engineering toolbox I got thermal conductivity of the two metals in question. Holley carbs until recently were always zinc die castings, the Aluminum Four Barrel aka AFB plus other Carter lookalikes including Edelbrock are aluminum.

Zinc - 116
Aluminum - 205

That's right. I don't care what gas you use, aluminum conducts heat almost twice as well as zinc. Meaning the fuel in the aluminum carb will get hotter.

WHY do you suppose Carter made the Thermoquad body out of plastic? I am certain that one of the reasons was cutting down heat to the fuel. That was one of the advertising claims, they made a big deal about it. They had probably really been hit with this as the EPA started cutting down on emissions from evaporating gasoline.

I could get started on the amount of ignorance showing in this thread, but why bother? Anyone else know what Reid Vapor Pressure is?

Much easier to bash.

Crying shame that you gave up on the AFB and went with the Holley.

I have owned AFB carbs since the late 80s and greatly prefer them over the Holley stuff. They tune nicely and have great street manners.
Yes, I have been able to get a wee tiny bit more power out of a Holley but it comes at great cost to mpg and street manners. I've even run the dreaded 750 AFB with good results.

It's your car so do what you want. In my opinion it's kinda silly to go through all that trouble when a 3/8" spacer will likely cure your ills.

Don't hold back , tell us what you really think ...

I never had a fuel boiling issue with a Carter before ethanol, but good point on alum transferring more heat, the carb on that 383 i mention above is a very OLD 650 DP, Zinc .

The Ebrock performer 750 is still a piece of junk , doesn't matter what fuel is run thru it .

Problem with that is the hood clearance with a stock air cleaner which he is choosing to use.

But I guess the question is what air cleaner is he using ? If it's the stock unslienced then a 13" Ford Motorsport open element base will work with it and drop the air cleaner top down.

But then there is the issue of the carb he is using

\

Don't bother , it's a 70 up E body , 71 up B body cable , won't work.

I contacted the seller before I purchased kit and he swapped cables for me before he shipped it out.
It looked the same as my OEM cable so left it as is.

Lucky you , The MP install kit that was sold for ever only came with the E body cable , that cable he swapped in , if not a 4bbl cable , is $$$

The seller was rob1426 and it probably is the 4 barrel cable. Out of all the kits for sale on eBay he's the only one that includes the choke and hardware. The fuel line blocks do not have the bottom notched but I can live with that.

Statement like that is just making you look bad...


My 'piece of junk' has been on top a' 440 for a coupla' decades...

Good idle quality...

Good transition...

Pulls good...


I can get in there and do dam near anything, without even taking it off the intake...

(Orifice/bleed passages;power-valves;bowl leakage-no worries...)


And still looks like the day I bolted it on...

Wouldn't trade it for the world...



You ought to just dive in...

If a knuckle-head like me can figure out an AFB, I'll bet you could, too...

... Knucklehead would be correct.

I've already wasted more time than I needed to trying to tune one, I sold my last ebrock carb at Carlisle and don't have anymore of them to deal with.

I have a Carter Competition 750 from the 80's/90's and a few stock AVS's if I really feel the need to be tortured.

The UNTOLD THOUSANDS of us who successfully run E-brocks collectively say, 'Rock-On'...


And come here to Stanton in a coupla' weeks...

Some of these dudes are WAY beyond 'knuckle-head'...


And dammed if they don't run Carter...

With surgical precision...

I didn't think that there was less than 3/8" hood clearance on any of these cars.
I understand a shaker car might have an issue but not a bulge hood.

Why didn't Mr Scientist get into the vaporization of fuels?

I'd like to see him cover all the different blends used throughout the US.

--- Well I installed a gasket today from Napa that without measuring I would argue is 3/8 or close to it and although there was an improvement it by no means came anywhere close to curing the issues. The improvement infact could have been purely the fact that it wasn't as hot today as it has been lately. Another reason it may have been so bad yesterday is the passenger rear bolt wasn't much more than snug so it may have been getting a vacuum leak at that corner, of course that was correct with the changing to the thicker gasket.

On another note I found I have a 3310 in my stash so I will fit it to an extra cast iron intake I have tomorrow and if it clears I will check the shafts for a rebuild canidate and it they are tight I'll rebuild it.

For the record I probably have about another 3/8s of safe clearance left under the bulge I can use.

Thanks for all the input folks this has been helpful and hopefully will help others.

Yep running the factory unsilenced air cleaner, good to know about the Ford piece although I assume it will immediately slow the car down. How much does it drop it?

Do they run Carters or do they run Edelbrocks ???

Because the Factory Carters and the Carter Competition 750 AFB IS NOT an Edelbrock Performer Series Carb

I love pulling this archive thread from over 13 years ago up every year

Look at the dyno numbers and read what he has to say about the Edelbrock 750 Performer Series versus say the Carter Competition
750 AFB

Proof is in the pudding per say as what was said in that thread
Dyno numbers don't lie and those carbs where both new , out of the box

1,000 Topics on the same subject - I will just leave it alone

Why anyone would waste there time and money on a 750 Performer Series when the 800 Performer Series is 100 times the carb is beyond me
It is what it is

the only carb that didnt actually run well was the Ebrock carb. it just didnt do anything well. poor idle, too lean everywhere, didnt take a load well, etc.
when i had a chance, i pulled it apart to see if there was any dirt or debris inside, and it was nice and clean. i also verified the calibration.
it was calibrated to the specs in the catalog.


thunderhead...regardless of the power output, the Ebrock carb had pretty poor overall manners. as for comparing stock vs stock, 7 of the carbs tested were "stock" with the as delivered calibration, and they all worked fine, except the Ebrock. since the Ebrock and the Carter are both made by Weber, and are basically the same carb, the fact that the Carter ran good and the Ebrock didnt just shows that Ebrock has the calibration set up for much milder combos.

one final note....
i dont have anything against Ebrock carbs. it seems some here have a hard time grasping that it didnt run well. trust me...it didnt run well. its that simple. its not hard to tell if its good or bad when youve already made nearly 70 pulls on the motor before installing this carb.
yes, the problems it had could be tuned out of it. thats obvious since the Carter 750, which is the same thing ran just fine.
it ran how it ran...which wasnt good.
this is one of those "dont shoot the messenger" situations.
