good ebayer, 57000+ feedback, was going to buy one from him for my regal, but needed to go steel for custom hinges.

If it's more of a performance vehicle, get a holley 650 cfm 4bbl, they tend to match up with a 350 better (unless it's cranking major power). A 750 cfm 4bbl will also work for 400+ hp/tq(demon and holley are about the same performance at this size, the demon is easier to tune), but no bigger and stay away from the trick ones, tri-power, six pack, dual quads, etc. unless its for show. If you're driving it everyday, get another edelbrock or stick with the one you have. Good luck

I dislike Holley carbs a lot and would advise you to run away from them. Too unreliable and fuel thirsty-especially the DP's!. If you need a bigger carb on a street car, a Quadrajet is the only way to go ( 750-800 cfm is a minute with a Dremel away!). You can order them from companies like Jet, etc. set up for your combination and you have a pretty worry free carb. If you must have new, consider an Edelbrock AVS. It is based off the old Carter AVS carb, and is an air valve secondary ( hence the name) carb, so you only get as much carb as your engine needs. It is a similar design to the Q-Jet ( I think it's available as a spread bore!), but has a few different features. Some say it is better than the mighty Q-Jet, and some say it is it's equal. I have never played with one, so I have no experience with it. I would also consider a spread bore because it has a superior vacuum signal at small throttle openings, and thus delivers more low end torque. The added torque means you need less overall throttle which leads to improved fuel economy.

My Quadrajet cost me $35. It was a fresh rebuild out of a van to which I cut off the stop on the secondary air valve door, and added an electric choke. It runs great, and cold starts almost as good as my EFI Nissan. It really is the only way to go on a mild street engine. Plus, you can take the money you save and buy something else.

I had a Holley 650 on a 350 with few modifications in an el camino. You have to tweak it a bit most every time you start up (but that's the aesthetics of it 🙂 ); it gives the most power out of all of them at that size. Quick fuel is another good performance one. (any bigger than 750 cfm in a lightly modified 350 won't give you more power and will suck gas)

unless your making serious power i dont think u should really need anything over 700cfm. i make around 360hp and my 650 holley holds up fine
