650 cfm Off-Road AVS Carburetors (Edelbrock)

Is this a good carb? I need a carb that is around 650CFM and won't kill my truck when I am off-roading.

Also should I dump the glass filter?

I'm afraid I don't have any experience with that Edelbrock. But I will say that I tried some other carbs, and ended up back with the Qjet. I've not had a single problem with it offroad.

There's a company located out of Cali that can custom build a qjet for you. It's call SMI Carburetor, and I read about them in Car Craft magazine IIRC. You fill out a form that has just about every spec imaginable for a vehilce: like cam specs, compression, weight, gears, tire size, etc. They quoted me $360 for their stage 2 Qjet. I haven't ordered one from them yet, but when I do get a new carb that's where I'm getting it.

Forgot to answer this question.

I would get rid of the glass filter. They make me nervous. I use a generic fram filter that is clear plastic.

These carbs are not good for off road use! Do not waste your money, although edelbrock makes a great carb for street I would have to recommend the Holley Off road carb or a good Q-Jet. Holley's are easier to tune vs. Q-jet which can be a pain sometimes.

Great carb! But not made for wheeling. Even with the offroad kit. Don't buy it. Go with a Q Jet.

Q jet, good throttle response, etc.

My Blazer ran THE BEST it ever has with that carb. I never took it offroad after I got the carb so no statements of its offroad performance. I have a friend that has one on his daily driver long bed and loves the carb as well.
