New Carb? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

84step · 02-22-2009, 06:09 PM

So i have been having troubles with my old q-jet latley and have convinced my parents to get me a new carb for a grad present. My question is what would be the best route to go iam thinking of either an edelbrock or a Holley street avenger either way iam thinking around a 650cfm, the engine is a 350 btw.

Most people seem pretty happy with the 1406 Edelbrock

I have a Demon that came on my B/B that uses Holley float valves, It would out of the blue start flooding going down the road. I strip cleaned the carb and installed new Holley float valves and it still floods. I will be ordering a new Edelbrock soon.

i would go with a holley its more of a user friendly carb and the parts are easily mixed and matched

84step · 02-22-2009, 10:36 PM

I talked to my friend who knows alot about carbs etc and he suggested to me that i get a holley street avenger 650cfm i think thats the way iam going to go.

Personally I suggest you get your hands dirty and try to rebuild the Q-jet. Then you could get something else for Graduation...

Not a bad suggestion. Rebuilding and tuning is the best way to learn how carbs work.

Primer70 · 02-23-2009, 02:16 AM

Q-jets are just about the easiest carbs to rebuild, and cheap to rebuild too. I'm considering running a Q-jet on my Suburban with the new engine.

*78 Chevyrado* · 02-23-2009, 02:33 AM

I've had 5 1406 edelbrocks on five engines and love em. they all work well, just pick the one you can work on the easiest.

60ratrod · 02-23-2009, 12:34 PM

my vote is for an edelbrock. you don't have to tune an edelbrock as often as a holley

Storm Chaser · 02-23-2009, 01:29 PM

I've had Q-jets and Holleys in the past, then a few years ago I bought my first Edelbrock... and haven't looked back since. When it comes to carbs, my opinion is Edelbrock all the way. IMO, they are much more user friendly than a Holley.

Damien · 02-23-2009, 02:01 PM

I would rebuild the Qjet as long as it is not the computer controlled version.

wicked_sky_gazer · 02-23-2009, 02:10 PM

I dunno where you all found reliable Edelbrock, i pulled a 2 yr old 650 off my truck (motor is a 355 sb) and replaced it with a new holley 680 about a year or so ago, the Edelbrock was a piece, i love the holley and would never consider going back.... not to mention my truck is much happier, and runs infinately better also

I don't know, they just work... no pwer valves to blow out, no leaky gaskets below the fuel level line, easy adjustability...

You mentioned pulling one off and replacing it- maybe there was something wrong with that particular one, who knows. But as someone who has owned many different vehicles with many different carbs over nearly 40 years, I'd have to say for a mild street engine (meaning not a race car), my prefs would be in this order: EFI, Edelbrock, a Q-jet in good condition and tune, then Holley. Again, just my opinion. I personally find the Holleys to be a bit finicky, bordering on drama queen, for something you have to depend on every day.

Alex1 · 02-23-2009, 04:57 PM

Holleys nolonger have PV issues BTW.

Go Holley and don't look back -Sooo easy to work on.

84step · 02-23-2009, 06:55 PM

Thanks for the advice guys I think iam gonna go with the holley, if i have any problems iam blaming you guys hahaha i also have a friend who has alot of mechanical experienc and he tells me the same thing that the holleys are good carbs and easy to adjust, imo i think i will remove the q-jet learn a little more and attempt to rebuild it and perhaps sell it later on.

thefatguy · 02-23-2009, 08:20 PM

I've got one of each. Actually, one is a rebuilt Carter AFB. So far, the Carter has been bolt-n-go (Q-jet replacement on a 454). The Holley is on a troubled 292, and I can't possibly blame it, but it's been a real bear to get to know (more my fault than it's). My buddy who builds dragboats likes both of them just fine.

Pyrotechnic · 02-23-2009, 09:03 PM

It's all personal preference. Each carb has it's pro's and con's.

I personally like the Carter AFB (Edelbrock) design.

BINGO !!!

Since I've been left on the side of the road a few times removing and re-adjusting float valves I want something other than Holley/Demon....

gchemist · 02-23-2009, 09:25 PM

I run a 1406 on my ZZ4. No problems. Easy carb to tune with a vacuum guage. Mechanical secondaries are a slight disadvantage.

Bow Tie Scottie · 02-23-2009, 10:01 PM

O.K. y'all, I've been away from here awhile. Last Summer I had my Q-Jet carb rebuilt. Since then after one minor adjustment (leaned out), my '86 C20 runs much better and on certain pleasant weather days it really shows. If interested here is a link that may help make a more informed decision:

Other than those 2 cents I looked into almost going the Edelbrock direction!

BTW, Chevy 350, engine VIN code "M"
