Title: Edelbrock or Holley
Post by: Rich on December 15, 2008, 03:11:05 PM
I need to replace my carb, and have narrowed down my choices to either an Edelbrock Performer #1407 750cfm or a Holley Street Avenger 770 cfm.  Which would you put on a 383HP with a mild cam (comp XE268H), Eddy performer manifold, ported 346 heads with huge valves, stock HP manifolds and 2 1/2" TTI exhaust.  Absolute max horsepower is not required, this car is driver more as a Saturday cruiser that loves to surprise Mustang GT's at stoplights.

Holley isn't my first choice. . .Ask Mobby what choice words I have used on a few Holleys.  Edelbrock gives allot less trouble

Eddy.
My Carter carb is actually identical to what Edelbrock makes.(same tooling)
I had a Holley on my car and it got tired real quick--plus I got tired messing with it.
I have an Eddy waiting to go on the Boab..someday..

I'm with Ron and pretty much everyone else on this.

Eddy... I had 2 holleys crap out in 3 years... Im pretty deep in the pedal alot and so far this eddy is dealing with it nicely...

But yea if you can do the TQ who doesn't like sewer pipe sized secondaries.... try to get one made 74 and down though... the later ones have more vacuum lines than david orreck...

No your not alone Stan, I have an Edelbrock and am less than thrilled with it.
None of my Michigan Mopar buddies like em either, they are all telling me to switch to a Holley or a Demon (although Demons are pricey)

In the early years ( (http://www.moparfins.com/forum/smileys/smiley9.gif) ), I always used Holleys cause the OEM Carters were %^$#.
I don't ever remember having a problem.
For some reason I started using the eddies only.  I dunno why.  I think it was because of the name.
Finally, after all these years, I decided to go back to my roots and threw on a Holley DP 750.  It ran perfectly out of the box with no tweaking.  The throttle and cruise control linkage snapped right on with no mickey mousing and operated perfectly the first time.
The secondaries open right on que with no bog or hesitation.  It starts the 1st time cold with one pump, and idles like it was fuel injected.  No farting, pooping, or stunble.
 
It was a true plug and play straight from the box.

Don't forget to buy the Chrysler adaptor for the tranny.  You know.  The one that nobody told you about until AFTER you bought the carb and went to install it?  (http://www.moparfins.com/forum/smileys/smiley36.gif)

Yeah, and you'll never see one of THOSE in a C-body (unless your some crazy guy named Jyrki...or one of those other crazy drag-racin' guys...Tony???)

My reman Eddy is just fine for now (a little stumble off idle when cold, but no biggie) Starts quick, almost like FI, does what I need it to do.

When the engine will get it's upgrades, then the TQ comes out (http://www.moparfins.com/forum/smileys/smiley15.gif)

In original form you did.  Hemis from the factory had dual Carters.

That's because Eddy boiught the patent from Carter when they went belly-up.  However, I've been told that you cannot rebuild a Carter using an Eddy kit, and vise-versa.
 
To answer the original question, I prefer the Eddy.  If you go with one I would recommend buying the re-jet kit for the extra 40 bucks.  Even at 750cfm you will probably find that carb on the lean side.  That's the usual complaint against these carbs.
 
I found it to be true.... (http://www.moparfins.com/forum/smileys/smiley18.gif)

All new aftermarket carbs are set up on the lean side right from the box.In most cases,you will  have to "set up" the carb to your application.
Fine tuning more likely...

The Thunders aren't as lean as the regular Eddy's  Haven't had to do anything to mine yet.

You miss my point.....most high performing or race engines use Holley or Demon carbs because they are more tuneable and can out-flow any competing carb.....

my Roadrunner is supposed to have a Holley on it because the air-conditioned cars got them

Hey Bobby, taking up your challenge, I just opened my files to some pictures I took of the March Meets at Famaso a few years back.  I looked at three pics of Hemi-powered rods.  The result: Eddy 2, Holly 1.
 
So much for "never seeing them."
 
Sorry Buddy, but generalizations always make me search.
 
I can post the pictures if you'd like.

Post by: Stitcherbob on December 18, 2008, 09:57:30 PM
I didn't mean Hemi powered cars...just meant full tilt racing motors....that's all


Most get Holleys or King Demons....check the Super Gas class cars at the track....

I finally went with an Edelbrock factory remanufactured Performer 750 (#1407/9907). I talked to Jegs and Summit, and both claimed that they have fewer problems/returns with the remanufactued carbs than they do with the new ones.  Apparently their rebuild techs take their time setting them up properly.

After some tuning I found it was still too lean, so I went  two jet sizes,one rod, and one spring richer and now all the flat spots are gone and the beasty runs as fast as it ever has.
