Holley vs Quadrajet

[nigsbro]

Hey there
I have a 80s k5 with a 350 sb in her fitted on it is a Holley 600 vac sec and im looking to get a new carb as im getting 6 mpg and shi..y pick up too.
I was looking at a Quadrajet or another Holley what is the better carb out of these 2?

IMO Q-Jet is the best. If you are looking for better MPG and all around driveability and dependability..
If you want straight line performance get a Holley. The stock ones dont work that greart off road tho.
The Holley truck avenger carb is a good off road carb if you want to pay the bucks they want for them.
But
You can get a rebuilt Q-jet that performs just as good and is better off road for wayyyyyy less.

If you are going to buy a new carb, my quick answer would be to get a qjet.

The Holley Truck Avenger is a good offroad carb, but I don't care what they say you are going to need to do some tuning.

It does depend on you. I like the Holley because I understand how to tune it better than I do a qjet. Plus I was able to get one slightly used off the internet for $250. However, if I had been buying a carb brand new I would have purchased a qjet from www.smicarburetor.com

I will second every word of that and add that I've heard good things about the edelbrock Q- jet.

I forgot to add im running a edelbrock performer intake manifold,headman headers and a 445 465 lift cam and flat top pistons would the quadrajet be ok on performance still?

Don't see why not.I'm running a Torker 2, Q-Jet and a 280 cam...

I agree with everything here. Unless you run a good size cam the Qjet is your bet bet. I have had mine on my truck for years, not one problem. The important thing is getting it set up right the first time.

 

[theperfectgarage]

The verdicts in... get a Q - Jet.

 

[ProJunkRacing]

I second you on that

My rebuilt q-jet will start my truck on it's side and while it is nearly vertical. It doesn't run smoothly or anything but it impresses me.

when my q-jet went bad i got a holley and loved it for 2 months then it went nuts, got a new one for free (warranty), loved it for 2 months then it went nuts, now i have my rebuilt q-jet and everyday i kick myself for paying $300 for nothing.
