1968 390 stock bore and assembly
Edel.Performer RPM
Comp XE262 cam
Headers
TKO600
63 Galaxie

Have been watching the classifieds to see whats available for the $$. I know i can pick up a new Edelbrock for around $250 then the price goes up fast. I know you get what you pay for but I want to understand what i'm paying for.

Are the off the self Edelbrocks reliable?
Why the big price difference in Holley, Dominator,etc.?

SmokinJoe has a Holley600 in the classifieds i thought would be perfect for me, but...

How hard are these to rebuild?
How much more money would i have into it?
Anyone on the site rebuild these? Ed Jekins?

All advice and guidance appriecated.

Kevin

what are your intentions with this engine

March 8 2011, 5:55 AM 

It all depends on what you are planning to do with your engine. If you spend more time on the street than on the strip i would go for a 750 performer edelbrock and no smaller unless you plan on modifieing it. I have melted a 390 down because i was using a 600 cfm eldebrock to race with and the fuel air mix got too lean. As a result i melted 3 pistons like candles. If you plan on a daily street driver the 750 edlebrock would fit the bill, right out of the box they hardly require any tuning at all and i used a 750 on my 390 for a daily driver for 11 years on my 390 and never did anything to it, infact i still have it on the shelf in my garage. So they are good out of the box for daily drivers. Now if the vehicles is a trailer-borne race queen then the holley line is the way to go. You will get more performance out of a holley for sure, but you better know how to tune one on your vehicle. I now run a holley on my truck but it is now a all out bracket racer trailer queen. When i switched to a holley from an edlebrock i droped 2 tenths of a second off my quarter mile time. You can run a 650 holley on your 390 if you know how to tune the main jets to your fuel needs to keep your fuel air mix happy. A keep point to keep in mind is the color of your spark plugs(new ones) for checking the jet size. The edlebrock 750 would give you a lot better fuel economy than any type of holley you could put on it, this is because the primary ventury are smaller than the secondary. I got a good 16 miles to the gallon on my stock 390 with the edlebrock, you won't get close to that with a holley.

650

March 8 2011, 5:56 AM 

I bought a Barry Grant Speed Demon 650 with annular boosters. I love it. I know BG has had some bad stuff but i gota a good one, although BG is now out of buisness, you might be able to pick one up cheaper now.

Not a fan of Ebok style carbs...

March 8 2011, 5:57 AM 

on a Ford no matter what.

A 600 Holley will do you well and they are simple to rebuild. Some carb cleaner, a large flat file to ensure mounting surfaces are flat and some time is all that is needed to bring one back to life. The worse part is scraping the original gasket material off the metering plate(if no one has ever been through it yet).

Usually any "used" 600 cfm Holley is about $50-75, unless it looks really new. A carb kit is $20-30 depending on how many pieces you get. There are basic field kits with just 4-5 gaskets, then there are kits with needle-seats and every little possible part.

There is nothing really to screw up when putting one back together.

If you plan on performance driving, then maybe a 750 Holley would do better overall. If you don't plan on alot of higher rpm driving, then a 600 will survive.

begg to differ

March 8 2011, 6:02 AM 

if you have never done any holley work, you will be lost. they are simple if you have the right mind set, but messing with just one thing like the acc. pump linkage will make you hate a holley if you don't know how to adjust them, they are the best carbs for performance on that i will agree, but you have to know what you are doing or be very brave.

I suppose so...

March 8 2011, 6:09 AM 

never looked at it that way. Guess maybe not everyone has the "sense" to be able to pick up and go? There again, if you just take it apart, clean it and put it back together(and if NO one has screwed it up previously) then there really isn't much to have to mess with.

another NON Edelbrock vote

March 8 2011, 6:23 AM 

Edelbrocks, Carters, etc simply do not belong on a Ford. A simple Holley rebuild is just follow the instructions that can be found on line anywhere. The same applies for any carb rebuild.

I HAVE to run the Edelbrock/AFB style carbs on some NSS applications and usually use a Damon Kuhn (Diamondback) unit that he extensively modified. That takes a cheap Edelbrock/AFB to a different standard and gets pretty pricey. We pull Holleys out of the box, do a few simple mods to them and bolt em on and go.

Yes, I have been building/repairing Holleys since 57.......same for the rest of the many carbs that have been used since year one......my choice has always been a Holley, NOT a Demon, but a real Holley over the rest if rules allow.

For a street car, I will always go with a Holley if the customer allows. Many have already spent good money for that dam Edelbrock performer package.......and we can and will MAKE em work for the customer's application, and to surprise some, those Edelbrocks don't always work out of the box either,..but I would rather put a Holley on and make it really perform. PUN intended.

If you never worked on a Ed carb, you will be lost! Metering rods are a pain in the butt. If you dont know what you are doing. My point is if you dont know how to make adjustments to a carb (dont care if its a Holley or Ed), then leave it up to a pro to do your work!!! JMHO

Holley

March 8 2011, 6:07 AM 

I don't have personal experience with Edelbrock carbs, so I will leave that to others to answer.

I have run holleys on my FEs for a long time. They are easy to find secondhand, easy to work on/rebuild/tune, and when dialed in they make the most power. They are modular, so you can upgrade parts of them as you want to tune them more. Most importantly, you can find parts very easily. For your car the choice would be between a vacuum secondary or mechanical secondary (double pumper). Usually double pumpers are for stick cars, but your car's cam makes it more of a cruiser, so you can go either way.

A 600 vac. secondary will work really well around town and have nice crisp throttle response, but will likely not make as much peak HP as a larger carb on your 390. I run a regular list no. 3310 holley 750cfm on my 390 in my galaxie. It runs great at low rpm and still rips to 6k rpm at will.

You can basically bolt one of these on your combo and it will run well (if the carb is working correctly and not been molested). Your other option in a vacuum secondary is an original CJ 735cfm carb from the '68-'70 time frame. Since these generally are going to need at least freshening before bolting on, you might opt for the new carb over one of these, but if you're feeling adventurous maybe go for it. A properly rebuild 735 is one of the best carbs for a street FE, since it is calibrated exactly for it.

With a stick you can also go with double pumper in a 650 or 750 size. I haven't run one of these so maybe someone else can comment on how they work with a stick, smaller cam and heavier car like your combo.

In the end, you can go with either the vacuum or mechanical holley in their basic model--stay away from 'street avenger' carbs entirely and you don't need the higher end HP carbs unless you plan on really digging in and tuning it like crazy. Here's what I would be considering:

Carb

March 8 2011, 6:50 AM 

Either Holley or Edelbrock. Holleys run very well when tuned and the typical List 1850 600 vacuum secondary is as common as dirt. If you give more than $100 for one you've been ripped and it better be in great condition at that price. $35 buys a full Holley brand kit at most chain parts stores. Rebuilding is not very complicated but attention to detail is required. Tuning parts are available separately and if you don't have a stash of spare parts, you will be at a bit of a disadvantage tuning one. A 750 vacuum secondary will run about the same and are also very common.

The Eds tend to run good out of the box in my experience. They make a great street carb and are better atomizers at lower street RPMs in that respect than 90% of Holleys. The Ed is a bitty spread bore design with a nice primary booster system. They have mechanical secondary with a weighted air vane, so they are a combination vacuum secondary type, not like the Holley at all. They are fairly easy to tune and are not as leak prone to the novice as a Holley might be due to the one piece base casting. They do have lots of small parts, clips, etc and require care in assembly. A tuning kit is more $ for the Ed but it comes with several tuning parts and a book that shows you everything about the carb and how to make changes in a systematic method to get results you want.

Either belongs on a Ford - I've raced both and driven both and both types work well. They really don't care about the engine make underneath. If you are concerned about max ET, then the 600 Holley DP will be about .1~.2 quicker in the 1/8 than the Ed 600, depending on the car. For drag racing, it's hard to beat a 650DP Holley - nice all around carb and can have good street manners too.

Re: Carburetor selection

March 8 2011, 8:36 AM 

Once this beast is on the road will be a cruiser for who knows how long. Once the bugs are worked out and more cash becomes available i plan on adding to the engine or starting with a new build, but that could be a few yrs down the road.

Thanks for all the replies on this one. I really wanted to put a Holley on it just so i could say i have one. Didn't want to through money out the door.

I've run both...

March 8 2011, 8:59 AM 

and I'm just not the kind of guy that wants to fiddle with a carb. Sure you can get max performance out of a Holley but are you going to notice it on the street? Most people can't tell the .2 of a second you are talking about - you have to go to the dragstrip to find out.

I dropped a 750 Edelbrock on my 347 SMF. Was surging a little in cruising mode so I dropped in a different set of metering rods. Took all of 60 seconds. That is all I have had to do to it. It pulls really strong, idles great, never leaks, never had to touch it again. Probably costing me that .2 but I would rather have the above attributes.

Same story on the stock 351C in my 73 Mustang. Let the Holley sit for a couple of months and it would start leaking when I would fire it up. Edelbrock took care of that.

Only problem with an Edebrock is that they will boil out the fuel easier than a Holley. Insulating spacer is a must.

I wouldnt bother with an Ed Carb~

March 8 2011, 9:13 AM 

I have played with both. Hands down for Holley! Easy to tune and they are reliable for sure. I ran a moded 750DP for years as a daily driver with adjust-a-jets on it. Worked very well indeed.

600VS will work just fine. If your wanting the the power, then step up to a 750DP or a 750VS. JMHO

Rebuild Kits

March 8 2011, 9:42 AM 

I've heard about QFT rebuild kits, are these the preferred kits for a 3310? Or, is it best to get the Holley 37-754? I had read in a Holley Rebuild book that the Trick Kit for it is 37-921 but I dont find it in the HOlley or Summit site.
Thanks,
Tom

Carburetor Choice

March 8 2011, 10:15 AM 

If I were building a basically stock Ford 390 I would say that a 625cfm Carter would be a good choice.

Back a few years ago I built a Ford 460 for my pickup and it was a mostly stock build. I ran it on the dyno and tested it with a Holley 750 vacuum, a Competition Series Thermoquad, the stock Holley and a 625cfm Carter. ALL carburetors were with 6 horsepower and 6lbs/ft.

I didn't know a carburetor had a way of telling what brand of engine it was bolted to anyway....
