New Carb Advise
I'm considering a new carb. I have a 350 small block Class 2 from Jasper. I've heard good things about Edelbrock's Performer 600 and I like the $240 price.
My questions are:
Is this a good carb?
Should I get a matching intake manifold?
Any idea what intake manifold or cam comes on this engine?
Is installation of either something for a beginner? :smash:
Any other carb recommendations? Better deals?
:cheers:

Yes, it's a good carb, not exactlly sure about your engine but chances are you might have to put in bigger jets in the secondaries to get it to rev up too 6000 rpm.:D But it's not a much of a job.
As far as the manifold I don't know what jasper has on them.

Re: New Carb Advise (foundvettelifeisgood)
Jay, what carb do you have on now? Check your manifold. Are there 2 mounting holes in the manifold for each corner?
I have an Edelbrock 1406, 600cfm, elec choke that I replaced with my present Holley. I only used it about 5 months.

Re: New Carb Advise (1970 Stingray)
Len,
I have a Holley 4011 circa 1920. :rolleyes: Maybe not that old, but who knows? The carb behaves well about 95% of the time. The other 5% of the time it seems to want to surge or flood. It also emits a strong gasoline odor after every drive and I get some subtle soot build up on my tips and bumpers. I could continue to live with it the way it is, but I'd really like to get rid of the gasoline odor in my basement, and I suspect that a longer drive in the summer heat will increase my chances of flooding out.:cry
I tried to study my intake manifold, but it was tough to see. There is writing on it, but I could only make out FIBI___ORDER, and that might not be right. I have an email in to Jasper to see what they may know about it.
Why'd you scrap the 1406, and for which Holley? If the 1406 is a candy-butt carb, please tell me. :lol:

Re: New Carb Advise (foundvettelifeisgood)
I switch out the Edelbrock because of clearance issues with the elec choke, throttle and fuel line. I was using the L-88 air cleaner assembly and the Edelbrock simply didn't fit. The L-88 base is a drop base and it was blocked by the elec choke, fuel line and throttle. It just wouldn't fit. The L-88 base was designed to work with a Holley and maybe a Rochester.
I got a Holley 3310, 750cfm. manual choke, vacuum sec, dual feed. It was incredible---the air cleaner base fit like a glove. A short while ago I added a Proform carb body to the Holley----Essentially now I have a "Jet" carb. The Proform body allowed me to use my stock SB hood with the drop-base L-88 air cleaner while I work on prepping and painting the L-88 hood. The Proform body eliminated the choke(which I don't need anyway) and the choke tower. This gave me the clearance I needed for the SB hood.
Sorry to be so winded! :sleep:

Re: New Carb Advise (1970 Stingray)
You better check to see if your air cleaner base will clear the fuel inlet on the Edelbrock. The Edelbrock fuel line enters the carb high on the passenger side rear. If you already have a Holley, then your air cleaner base should fit any Holley----whether it'll fit the Edelbrock with elec choke, high fuel line is another story.
If it were me, I'd get a 600-650 Holley double pumper, with no choke. I'm just guessing, but you probably drive your Vette like I do---usually on "Nice" weekends, avoiding the rain, salt & snow---so a choke doesn't matter to me. It takes a few more minutes for it to warm up but I don't mind. After a few miles down the road that Holley is ready to go! :yesnod:

Re: New Carb Advise (1970 Stingray)
Len,
What started my quest for a fuel line and then a carb was that my Holley fuel lines were so high that they kept the air cleaner from seating on the passenger rear side. The extension from the choke housing kept the Summit fuel line from reaching the carb.
I guess the new Holley's have a 45 degree approach for the fuel line versus a high vertical approach. Right? Are you saying that the Edelbrock only has one fuel inlet?
I want a good reliable carb that I can slap on and not have to mess. One that doesn't smell like gasoline, and that doesn't create a clearance issue. Is there such an animal? What about Demon's?
Also, I do need a choke. I drive this thing with the T-tops off and the heat blasting when it's 40 degrees outside. Bad case of the fever.:crazy:

Check out a Jeg's catalog, you can see pics of the different Holley's and the fuel inlets. There's a bunch of different one's. I think you have one with horizontal fuel inlets. The Edelbrock is the same except it has only one fuel inlet at the rear. I would think the one you want has angled dual fuel inlets.
I just checked Jeg's(htttp://www.jegs.com) catalog and they list a Holley 750, vac sec, elec choke & fuel line for $239----# 510-O-80508S.
There's a 650 there too for $334.99 # 510-O-80783C.
This one has a manual choke: # 510-O-4777C-- $284.99
These might be old prices though.

Re: New Carb Advise (1970 Stingray)
Ganey,
Thanks lots. Chime in with your recommendations. Is the stock manifold something I should consider replacing?
Len,
Did you notice the 7 TQ and 9 HP when you switched from the Edelbrock to the Holley? I realize every little bit helps, but I'm more interested in reliability and consistency.
Edelbrock has recently come up with a special fuel line that hungs the side of the Performer 600 carb and exits at its front. This may eliminate the clearance issue. If the other components don't create a problem for me, I might want to buy your carb if you think it's a good one and you want to sell it.

Check out the prices at for carburetors at this web site. A friend of mine had good service from them and the prices seem to be good.

Re: New Carb Advise (MIKER)
Jay, I can’t really say I noticed any difference in the engine performance. I do feel that the Holley ran better than the Edelbrock. The Holley seemed to run better right outa the box. The Edelbrock 1406 I bought to replace the 1405 which self destructed on the short drive home right after I bought my ’70.
The Edelbrock is a good carb and almost new. I bet I didn’t drive move than 800 miles with it. If you want to give it a shot, I’d even help you put it on. If it works for you great! If not---no problem.

Re: New Carb Advise (1970 Stingray)
I've heard great things about the Holley Street Avenger. That's what will be getting the fuel delivered in my Vette. I had an Edelbrock. There probably the most simple and trouble free carbs out there.

I am running a 1406, 600cfm electric choke edelbrock its great, I am running
a triangler crome air cleaner that came with a 3 in. air filter I changed that to a knn filter that is 2 1/2 in. plenty of hood clearance :D I am also running a jet coated eledlbrock preformer intake it woke up that sleepy L48
in my 76 let me know if you need any photos
good luck
the form rules :chevy

Re: New Carb Advise (foundvettelifeisgood)
I installed the Performer 600 cfm on my ZZ4 there was a slight interference on the stock double snorkel air cleaner but edlebrock makes a 90 degree fuel line fitting and a slight modification on the underside on the air cleaner allows it to seat properly :cool:

Re: New Carb Advise (Chris Butchart)
My L82 has had many of them. Edelbrock 600's and 750's need the 90 degree brass fitting to clear common after market chrome air cleaners. With jetting changes and understanding how they work they are wonderful carbs. The 600 is good for 355ci to the 375hp range. being vac secondary they are okay to jump to 750 cfm with 355 ci in modified motors.
Road Demon is also a good choice for low end. I mean lower sub 375 hp motors. double pumpers are for people that know what they are getting into. I would like to try a 750 speed demon Vacuum Secondary. I jumped from a 750 speed demon to a modified 750 to a 825 cfm Race Demon. I'm happy with them all. In year past i ran Holley double pumpers on other cars. I have no knowledge of the new holley Avenger series. so they might be another option.
I have my old perfect 750 Edlebrock on the shelf. I ran it for over ten years with all kinds of motor combos in my vette. I know enough about them :seeya

Re: New Carb Advise (gkull)
What type of carb came originally on your engine?
Have you considered putting a Q-Jet back on? Edelbrock sells them new (#1901 for the pre-73 models). They work fine off the shelf, but you'll want to e-mail lars and he can get you the correct Jet/Rod/Secondary combination that's right for your motor.
Or, Lars may have a core he could rebuild for you and sell inexpensively?
The other nice thing is that all the parts that you order for you carb from the Vette vendors will work. Every part I've ordered from Doc Rebuild, Ecklers, etc. has bolted right up to my replacement Q-jet!
Just a thought...
