Edelbrock or Holley

[Scott Engelhardt]

440 built to stock specs. I have a Holley 750 on it now. Car runs pretty good every place other then off idle tip in. I have been trying to tune out a tip in stumble. I have changer accelerator pump squirters and have changed the cam out. I have played with this quite a bit and maybe I am expecting too much from this carburetor. I like the fact that the Edelbrock won't leak fuel every where when tuning.
Any thought pros or cons would be appreciated
Thanks

Both Edelbrock and Holley have their pro's and con's.
In my experience with both (and not a knock on the carbs themselves) I'm going Sniper FI. It's the fuel, not the carb.
Again, this is my experience...and I've been tuning my set-up for quite some time.

Could be timing. It should be optimized before getting too involved in the carb. IMO, Eddy's are for a mostly stock engine. Holley, and their variants have alot of parts, and customer support. Some have glass sights to check fuel level. They come in many varieties, to fit many different applications. Also, not as prone to heat sink either. I would try to optimize my timing, then give it more fuel at the pump/squirters. If no luck, consider a Holley variant.

I'm a fan of the good old AFB (Edelbrock). I agree with the timing adjustment. Usually takes a few degrees at a time advance to get rid of the stumble.

With either carb tuning could be a long process and I was never completely satisfied. After switching to race fuel, tuning was MUCH quicker and easier and with an engine that ran and responded as it should.

That being said, I prefer the Edelbrock for ease of tuning.

dla4567, hit a good point.Its' not so much as your tune. I strongly believe it's the quality of pump gas now-a-days.

Lack of quality would be more accurate. It’s truly garbage. You can still buy ethanol free at a couple local stations, but the crap they sell today is horrible when used with a carburetor. At least with EFI, the fuel pressure is higher which raises the boiling point so there are no empty fuel bowl evaporation or vapor lock issues.

I prefer the Edelbrock AVS2 Series carbs. I have an 800cfm AVS2 on my 440 and it is a great street carb. Annular primary boosters make tip in lean non existent. Very smooth and responsive transition.

The Eddy is about as easy as it gets to tune. Rods and springs take nimutes to swap. Jets would take 10 minutes if you take your time and no fuel spill.

The Thunder series has dual feed if you do desire. I also have a 600 cfm AFB Edelbrock carb on a 318 poly and it has been bullet proof using stock settings.

Both have phenolic spacers, the poly is stock fueling. The 440 has an in tank fuel pump and external regulator.

The best pump gas I can buy locally is 91 non ethanol. I have played with the timing and it still is there. Like I say maybe I expect too much from that Holley.

If your Holley is spilling fuel in a turn, you have a serious problem going on. Lower the floats!
As far as which carb to use. The answer is which ever the be you feel best about working on.

It's an off idle tip in stumble under light acceleration

Off idle light throttle is usually in the idle circuit. So the idle mixture is too lean, and/or you have pluggage in the idle/transfer slot.

What is the initial set at?
