quadrajet vs. edelbrock
 

ok guys ive done some research via google and would like ur porfessional advise now

i recently changed my quadrajet out for a new 600 edelbrock, and i lost almost 8 mpg.

everything im reading says the quadrajet should be more fuel efficent then the edelbrock due to the quad being spreadbore.

so should i hunt down another quadrejet and junk the edelbrock?
any of you guys have any advise eather way?

I would say go back to the quadrajet because if you get it set up right it will be a very good setup

Re: quadrajet vs. edelbrock
 

my stock 83 suburban with a CCC Quadrajet got 22 MPG average on one of my cross country driving trips. I was drafting Semi's a lot of the time, so that definitely helped, but I usually average 14 to 15 with normal highway cruising

Why did you remove the q-jet? was there a problem with it?

Re: quadrajet vs. edelbrock
 

Sorry to hijack the thread:
I have an edelbrock on my 460 BBC in my Burb, and have been considering swapping to a QJet....does anyone have any experience with the Summit Racing rebuild units, the universal ones set up for BB?

I have never dealt with a remaned q-jet, but I've read and heard a lot of bad things. Your best bet would be to rebuild it yourself. Get Cliff Ruggle's book and study it before starting. Really, they are not as complex or difficult to work on as everyone makes them out to be. A big problem with them is worn throttle shaft holes, but it really isn't that expensive to have new bushings installed ($8-$20).

The thing is, I don't have one now.....

Re: quadrajet vs. edelbrock
 

Used Qjets should be pretty plentiful since a lot of people replace them. Try posting on Craigslist.

Check the sale section on this forum also, someone may have one for sale.

i removed the old quad because it wouldnt idle, and didnt run so great, and my friend gave me this headache, i mean edelbrock, and like a dummy i gave the quad away

Re: quadrajet vs. edelbrock
 

The simple answer is that Q-jets are great carbs; the spread bore, unique construction and huge flow capacity makes them one of the best street carbs of all time.

The downside is that they're typically in lousy shape, and there are very few rebuilders that can do them right. Tuning parts and expertise are also tough to come by.

Your Edelbrock is fine - it just needs some tuning as it doesn't come tuned "out of the box".

Re: quadrajet vs. edelbrock
 

got a nice quadrejet today, bolted it on and GLADELY throwed the edelbrock into the scrap pile to take to the crusher.

Re: quadrajet vs. edelbrock
 

It took some work but I am getting better economy with an edelbrock. you just have to tune it down.

Re: quadrajet vs. edelbrock
 

Insanity.

They are damn good carbs. Something was surely wrong with yours to lose 8mpg versus a quadrajet. I'm not saying they're better than a quadrajet, but yours had something else very wrong with it. I'll take every Edelbrock or Carter AFB I can get. They are the easiest carb around to overhaul and mine have always worked very well.

Q-jet or Edelbrock???

Dang.......that's like asking two "short" school buses to race each other!

(LOL...did I just type that?):lol::lol:

Re: quadrajet vs. edelbrock
 

how much to ship it this way?

Re: quadrajet vs. edelbrock
 

Tell me you did not throw a NEW carb away!?! I have one and it runs great, you just need the kit from Summit that has the springs and metering rods to adjust it to your application.

If you did, I'll pay shipping and you can send it to me....
