If you were going to replace the stock carbs on a 69 426 street hemi, what would you use.

Stock engine with elect igntion and firewires.

Just using for pleasure driving so reliability and close to stock look is what is most important to me.

Thanks!

Give me a call. There are some things you have to think about when switching to edelbrocks. I have done about 150 set so far. 586 726 6900 Jake

Many years ago I used a pair of Carter Comp Series 625s. Had to fab some linkage and fuel lines and a new air filter base. Ran good when it was all done.

Or you can buy a set of the Hemi "clone" carbs that I sell. They utilize original small opening tops, a modern Edelbrock carb base (CFM size of your choice, bodies finished to look like originals, not shiney like new Edlebrocks) reproduction correct Street Hemi side linkage, and any style choke, automatic OEM, Manual OEM, or Electric.

All carbs are shipped complete after being test run on a mule engine after having a thorough restoration overall with correct finishes and plating throughout so that they look as good as new and run even better.

All original/stock Street Hemi air cleaners, fuel lines, progressive linkage, brackets, etc. work on them, and all modern Edelebrock tune up parts, jets, rods, etc. work in them so tuning is easy.

See my website for pricing, or feel free to give me a call if you have any questions.

Scott , have you had any customer complaints from any clones you sold based of Ebrock 750cfm carbs ? It's been well documented that these carbs run like crap as sold by Ebrock , what are you doing to correct them ?

Most customers do not choose 750's,(since 600's work super on even moderately pumped up street engines) the few sets I've done using 750's (mostly on big cammed/compression or big stroker race engines) have had no reported problems. That being said I leave no stone unturned when I build these carbs, I do a 100% tear down whether new or used and process them as I would any other carb I restore, this even includes throttle shaft bushings. If they did have a problem to begin with I likely eliminated them in my normal process. This is the last set of 750's I did (this month).

I believe EB had a bad run of carbs recently (not sure what parts were bad), but based on the numbers I've seen for sale at several shows recently as "factory remanufactured" it must have been a pretty big issue, and it didn't just include 750's. I think EB reccognized and tried to take back as many as possible and repair or replace them to put the problem behind them. Most of the cores I use have been in my inventory for several years now, I'm guessing they are "pre-problem" examples.

If you use the new Edels. your original air cleaner base won't work.

Go with the eddy 600's. I know several members are running those carbs on their dual quad 440's.

There are 2 basic reasons why out of the box Edelbrocks won't work as direct replacements for an original 426 Street hemi using the other original Street Hemi intake assosiated parts (Air Cleaners, Side Linkage, etc.).

To make original air cleaners work you need the smaller diameter/vintage carb tops, all modern Edelbrocks have the large diameter tops and will not work with vintage air cleaner bases.

To allow the use of all factory progressive linkage parts, throttle cable brackets, return spring set ups, etc. without adding modified or custom made parts you'll need to remove the stock Edelbrock side linkage arms (they are welded on) and replace them with reproduction Street Hemi throttle arms (also welded on). That's just the basics, there's more time and money involved in performing all of this than one might imagine.

While OTB Edelbrocks will bolt on and work on a stock street Hemi intake, it's the small stuff that comes back to haunt you. To accomodate the larger top openings you'd need a custom air cleaner (some steel versions are big bucks) and you'll need at least some mods to the stock progressive linkage setup, etc. Add the price of new Edelbrocks to the cost of the special side linkage and air cleaner required (not all styles are available BTW) and you'll soon find that it's pretty expensive, and when you are done it's still not as stock appearing as simply adding some converted "clone carbs" allowing you to use 100% of the factory air cleaner and other componants.

I bet hybrid fiberglass solutions(moparts member PAINT IT BLACK) could hook you up with a fiberglass base made for your needs or a generic one you can mod to fit. You could then use an edelbrock progressive linkage kit. It won't look stock under close inspection, but seeing as it's all hidden under the air cleaner anyway nobody will know.

Yep! If you want to go fiberglass and the other mods mentioned you/he could certainly do that. Just depends on what each persons expectations are, and regardless of that choice, don't forget, if you don't already own a set, a new pair of Edelbrocks aren't free, do your shopping before you decide which way to go, the total investment difference (starting from scratch) is smaller than you might imagine.

Hey it is what it is John, what has not been posted is that unfortunately (at least one member whom has contacted me after seeing my posts here) has already purchased some rather expensive new Edelebrocks which now leaves mine as a costly alternative, I can easily understand why he wouldn't want to spend similar money twice.

My posts were mainly directed at others who haven't gotten in quite so deep yet. As you know, there's allot of other componants to consider other than just the bare carbs.

The other consideration that has not been mentioned is future value. Original or reproduction parts (air cleaners, linkage, and other assosiated parts as well as clone style carbs) will bring more money than a set of Edelbrocks and custom parts will if resold seperately, or in the overall value of the car they are on if sold down the road, maybe not a popular area of discussion but it's something many do consider important.

You're right scott, it all depends on what a guy's going for. If it were me, I would be more likely to pick up two used eddy 600's, rebuild them and do the fiberglass base. For me it would look 'close enough' to stock and I could throw all the stock parts into a box on the shelf. But if you're pickier about originality and want a lower effort alternative I think what you're offering is great.

Do you really want to get into this?

They are neither clone or tributes they are modified Edels. to fit the original air cleaners. i was asking if you had an original set of factory 67 "cheater" carbs as they were known that flowed 750 cfms in th smaller bodies back in the day. i assumed that you knew how to read the numbers on them to identify them but maybe not.

Look DONKEY , they are CLONE carbs , they have NO NUMBERS on them , I know the source of them , and I know they are NOT the 67 cheater carbs ... more than likely they are Ebrocks and I hope they work ok, if they don't I'll have to find another old carter AFB 750 like the one I have and have them made into clone , er tribute carbs and off these .

Sorry for addressing this ancient post.. just getting back into things here after a break.

Scott, I appreciate your approach and not stooping to diss fiberglass or my company. We have a mutual respect.

That's why I do what I do.. there's all sorts of motivation factors in what one guy does vs. another.

Here's the base I offer for the record. Actually, the rear hole on this one is too far back because this one fits a Staage V setup, but this is essentially what you can expect, but that it will fit a couple of Eddy carbs. Once painted.... hardly noticeable that its not steel. 3X as thick as you'd expect, so you can smooth the underside if you wish. No warpage or any other pit falls. Plenty of people here can attest to that.

Are you having issues with your stock carburetors? Why not have them fixed or repaired?

Let me tell you from first hand experience, had I known about what Scott had to offer, I would have gone that route. But the engine guy put 650 Thunders on my motor, and I wasn't going to throw them away, but every single thing between the intake and the air filter was a can of worms. It always costs to deviate from stock.

I am building a 70 date coded street Hemi with the street Hemi stock intake manifold. I want to buy some Edelbrock 600 cfm carbs for it. Which ones should I buy? Should I order one carb with the electric choke? The car is a manual trans also.

Haven't you been reading the thread? Sounds like you are going to make the big mistake Scott was talking about above.

Personally, I'd like to see a setup with four Weber IDA carbs with short stacks ending up inside the 2-4s air cleaner. Talk about an interesting build for the cleaner base, but it'd be way cool.

Just another way of looking at it.

Here's a pic of what I'm talking about. These are based on Edelbrock carbs (the bases only) and the tops are old original carters that fit ALL years 426 Street Hemi air cleaners. These carbs use all of original parts (linkage, fuel lines, etc.) with zero modifications. Choke shown is electronic, I can add any style choke desired, and please ignore the incorrect fuel fittings, they were just on there for the test run.

*JohnRR, I can also build these clones from older Carter Competition Series carb bases (as opposed to Edelbrocks, which by the way I have had zero complaints about) but you would need to find and supply the bases, I don't have a ready supply of them.

When these HEMI's were built, the front and rear carburetors were different. The rear carburetor was the one primarily used for light throttle/cruise conditions. Hence the progressive linkage that brings in the front carburetor for wide open throttle. With Mr. Harms work above does the linkage operate the carburetors 1-1 as essentially these are the same carbs. being an Edelbrock 600, 750, etc.. Or, have the idle and cruise circuits been modified on the rear carb. to allow the use of the progressive linkage as original?

$600.00 each.

Yes, as mentioned these use the exact same progressive linkage, fuel lines, etc. as factory carbs. These are not off the shelf Edelbrocks, about the only things that are "stock" Edelbrock are the bare base castings and some of the small common parts.

I've sold A LOT of these over the years with quite few of them being from return customers, they make a very nice economical setup for any street driven Hemi and even for some Race Hemi's, especially considering that original Hemi carbs in restored condition commonly trade hands for $2,500-$6,000.00.
