what carb would i buy to replace a carter quadrajet on a 400 cid 4 wheel drive? i am looking for a combination of power and efficiency.
edit: sorry, its a 1976 chevy original motor as far as i know. not sure what kind of manifold it has (how would i check it?) current carb is a carter quadrajet.
Sutton

what year is your truck? What intake manifold do you have? Do you have a rochester quadrajet? What's wrong with your carb?
-
Well im sure ur going to here Quadrajet alot...But im a holley guy myself....
But i must admit the q-jet combines power with efficiency while holley is more about the performance

Edelbrock puts out the the Carter/Weber AFB series carbs which are decently priced and easily tuneable. They've proven their worthiness in many dyno test results over Holley without as many problems. Personally I had a Dominator on my 454 and tuned and tuned and tuned that carburetor with little consistency so I opted for an 800 Edelbrock. I had it tuned and dialed in so easily I decided to eBay the dominator. I have an Edelbrock Q-jet that I scored for free on my 86 K20 and it's pretty decent. So I must say the AFB style carbs are the easiest most user friendly carbs if you're not the best tuner but even so they perform quite well.

Hey my pleasure. In my little bit of free time I get I like to come here and help. It helps me keep my brain tuned too!

Your best off getting a Rochester, avoid square bore carbs. and I think as long as the rest of the engine is stock, it will be happy with 600-650cfm.
-
Holley Truck Avenger for serious off-roading or rebuild your Rochester for optimum performance and effeciency.
-
i recommend the "Eldelbrock performer series carburator - 600cfm"
-
I second the edelbrock.I just put on on and it is awsome.
-
yep, VZ is one fart smucker...we are lucky to have him around. now that i've made his head three times bigger, onto the comment i was gonna make...for off-roading, as much as it ticks off most QJet haters...the good 'ol Quadrajet is about the best carb you are gonna find. it is just really well-mannered off road when it's in good shape.

I agree
