i run a 600 holley on my sbc for years no problems we just built a 292 y-block 60 over with a mild cam a buddy got me a new eddie cheap so we put it on so far so good
Holley sells tuning kits for the 4150/4160 series carbs... Look them up in the latest Summit catalog in the carburetor section.. You get a bunch of goodies in those kits including stacks of new gaskets...
I find that most carburetor problems are a failure of the installer or tuner. To vilify one brand while favoring another often stems from ignorance, rather than anything else. All carburetors need to be selected, calibrated and tuned for the individual application, and where and how that application will be used. Read this as many times as it takes to sink in: No carburetor is ready-to-run out-of-the-box. Read the manufacturer instructions, and follow them. If you can't do this, take it to someone who will. If you fail to do this, your results will only vary by the degree of failure. This failure will be your fault, almost without exception, so don't go running to a megaphone to blame the manufacturer. It is a near guarantee that you will make yourself look like an idiot.
I dont' know about edelbrok carbs from the 80's... I always ran Holley's, but i do know the newer model edelbrok are pretty dang good, but with every motor it may require some tinkering. I run a Holley on my 54 chevy and will run an edelbrok on my 30 sedan
Chalk and cheese comparison A double-pumper is not a good 'street' carb, a vacuum secondary model would be a closer match to the Edelbrock. I noticed one or two on this thread doing similar comparison too. I've used heaps of 600 vacuum secondary Holleys and only one gave me grief - and that was due to a split in the float.
Got just what you need even better check my classified add. http://www.jalopyjournal.com/forum/showthread.php?t=614062
x 2 And as far as asking if an Edelbrock is any good your gonna get people telling you one is better than the other all day. I am running 2 Edelbrocks on a 350 and a 460. 2 Holleys on a 350 and a 396. So I'm pretty neutral on picking one brand or the other. Im happy with both. I would rebuild your carb or send it back put it back on tune it and then see if your happy with it. If not you can decide if you wanna go Holley or Edelbrock. But you seem to be already shying away from Edelbrock.
I like edelbrocks for me they seem easier to dial in. One of my good buddies swears by Holleys and uses them on his circle track car and man they run bad ass. When I tried a holley my results were not so good, untill he came and tuned it and put me to shame. Go figure
the wagon in my avatar 383 with 2 1406 edelbrocks runs strong, pulls hard.alittle dailin in is all it takes.o/t nova 355 11 to 1 sbc.2 1406 edelbrocks.runs really strong. i like edelbrocks. ive run holleys for years.on tunnel rams and regular 4 barrel intakes. no problems . just have to use the right carb for your app. and dial it in.
Nailed it on that last part. And it doesn't matter what carb it is, you HAVE TO dial them in if you want them right. Which sometimes means you have to at least read a manual to know how they work and how to tune them.
90% of carb problems are electrical in nature. Proper inlet pressure of the fuel for the system is critical. The tuner must think like and understand the system. Some tuners only "speak" holley, some only "speak" carter, some only "speak"rochester, and the same for NA, boost, alcohol, nitro, injection, on and on. Some "speak" fluently in all fuel delivery systems.
Listening to this guy is an absolute waste of time, he is the one who told me that Edelbrock doen't know what it's talking about when it states in its manual "does not require a pressure regulator" wanted to call the tech an idiot and now he wants you to read the manual! I've returned 2 Edelbrock carbs. that were defective and thanks to Summit finally have one that works but still feel strongly that their quality control is horrible. Don't know about Holley but the next time I'm going to give them a try
Lol you're funny, if your pressure never goes over 5lbs. then you're probably ok with no regulator, but that happens very rarely, and to blindly think that their tech support gets it right all the time is bullshit as well. I guess your reading comprehension is bad as well, I said "Which sometimes means you have to at least read a manual to know how they work and how to tune them." But then again my Edelbrock's work and you had to send yours back. As a matter of fact I have taken many that people swear are bad and had no issues with them. When you call someone out you might want to have some knowledge to back it up. You don't...
I just went thru this Crappy idle Barfing gas onto the intake manifold hard starting etc I put a summit brand (holley) fuel regulator fixed alot of it my timing is still off but at least it idles/starts better/doesnt flood. If I could do it over id see if summit sold a 'white box edelbrock' fuel pump. Plumbing the regulator was ugly but worked a edelbrock pump would look alot cleaner Set floats and check your fuel pressure with a decent guage and report back. Tons of info on google etc about this subject.
Funny thing is there are a ton of others that advocate the pressure regulator despite whatever the hell Edelbrock's minimum wage tech support says. Yet you continue to take their word and won't let it go. You're wrong, get over it already. And in this day and age you have to take any new carb apart and check it before putting it on, that's reality. You also need to learn to use spell check.
I continue to be amazed at your "ability" to decide only you know anything about anything and I'm certain Edelbrock now shares my enthusiasm for your knowledge with the "minimum wage tech" statement! My issue with Edelbrock includes a carb. with the idle screw so tightly turned in (in spite of the manual saying it was shipped at 2.5 turns) that they wanted it back in case the base had cracked and a carb. that the float pins were actually bent- I realize it is difficult for you to understand that most of us do take a carb. apart to check it! It probably is beyond your comprehension but based on my experience I do believe Edelbrock's quality control is horrible and their carburetors are junk. I will pass on your next response as I don't want to waste other people's time but I do leave you with my opinion of you .....
Wow you sure do sing a different tune than you did in the other thread... and tell us more about the ex Roush mechanic, that was funny too... and even when you admitted that the pressure was ranging from 5-7 lbs., you're always good for a laugh...
Ran it 1 year (93) parked it till 2005 and have been putting up with it till now.. Just want it to be right.. Dont have deep pockets so am doing as I can.. Thanks all for the good info.. John
While I'm no carb expert I have fooled around witha few. The BG Speed Demon 750 w/ annular boosters was the only one I gave up on. POS came full of aluminum shavings and the "Idle Eze" feature was a joke. I've had Holleys, E-brocks, Carters, Strombergs and had pretty good luck with them all. Fuel pressure is important as is all the other carb settings, but don't forget about your timing and vacuum source (if running vac advance). Had a holley that ran great but had a slight hesitation off idle that I just could not get rid of. Finally switched to manifold vac, problem solved. Just curious about the blanket statements always made about "too big" and double pumper "not good for the street". I run a 780 cfm Holley DP built by Pro Systems on my small block and it is hands down the best carb I have ever run. More responsive, better idle and mileage than the vac secondary unit it replaced. I questioned them about the size, too big?, but went with it. Of course, they're pros and have a wet flow bench. OP, get a strip kit for your Edelbrock and play with it. They're pretty easy to work on.
there is no such thing as a universal carburetor.the factory spent hundreds of hours calibrating them for the particular engine and usage.i have been a professional driveability auto tech for 25 years who has rebuilt literally hundreds of carburetors.the factory doesnt always get them right either.the holley four barrel needs to be set up correctly to get the best performance.i have gotten as good as 22 mpg on a pretty hot sbc.edelbrock carbs are based on the afb much older tech.still good but never as much power as a properly tuned holley.how many drag cars you see at the track running in the tens or better got a edelbrock or afb or even a rochester?maybe 1 out of 50.honestly never seen one at all but im sure somebody on here gonna say "jethro runs tens on the street with his edelbrock carb and performer intake!"( which is is b.s. too).the edelbrock is a little more idiot proof than the holley.bottom line YOU HAVE TO TUNE IT to make it work right.all 4 barrel carbs run best around 5-7 lbs of fuel pressure.(2 x 1 barrels / 3 x 2 barrels run around 3 lbs)ive run more "junk holleys"than i can count with zero problems.get a book on carbs ,read it ,learn how to set them up.oh yeah make sure your distributor is set up correctly ,all engines can benifit from a properly curved and timed ignition system that delivers a consistant strong spark.
Well, I'm not Jethro, but....... It would be interesting to look at some of the records for Stock (and doesn't Super Stock require OEM carbs???/ OK, I just looked and it reads any OEM carb or replacement which leaves things pretty wide open). I'm sure there are a few AFB's (factory 426 Hemi's?) and Quadrajets that do a pretty good job when they are what's required. But as has been pointed out, it's all in the tuning. Larry T
uh yeah dual quad cars,ok .put your edelbrock 750 on the dyno against a 750 holley see what happens considering they are both properly set up.this has been proven over and over again.im not sayin the afb or edelbrock copy are bad carbs there just a more more of a street carb,and if thats what he wants then so be it.i just happen to know how to make holley work on the street and blow past the edeljunks.i like em because when im racing against em they,re easy pickens . most stock and superstock cars are in the 10s and 11s by the way.
I put these on my 355 SBC 5 years ago and have never touched them and have never had a problem. I love my Edlebrocks.
Funny thing I was really happy with the one on my Buick as well. Then I spent an hour on the dyno with mine back in August, wow did it make a difference. I had it nailed from the bottom end to the mids but then it got a little off. Fixed it up and it's even better now.
