600 vs 650 Edelbrock Carburetor

[fischebc]

I have an 85 chevy 4x4 with a 350, well I'm assuming that. I got the Chevy Engine Code Suffix from the pad right behind the alternator the last letters are CHS, I looked that up at http://www.nastyz28.com/ and it's correlating to a Camaro 350. So back to my question, on a 350 with headers, exhaust, and stock intake should I go with a 600 vs 650 Edelbrock Carburetor? I plan on buying a boat and eventually getting a performer RPM intake as well.

      If the internals of the engine are stock, the 600 cfm should be fine.  If you are looking to supe it up later than just get the 650 now.

Concur.  I'm not sure it's possible to exceed 600 cfm on a normally-aspirated 350 with a 5100 rpm redline.

600, a couple airhorn gaskets, and the tuning kit. they are easy to tune and fun as well. Cheers!

X4 first mistake most make is throwing a big carb on a engine. but just because i can, whats wrong with the quad you have? most think they are no good but a good rebuild/tune they will out perform most carbs

[rich weyand]

Just about any of the common carbs, when well-tuned, will outperform any of the others that aren't. 

Do the work.  Most people don't.

I've got both carbs, a 600 on my Chevy and a 650 on my '69 383 dodge (definitely a carb for a slightly hopped up engine). My 350 with the eddie 600 & Performer RPM intake was a good combo choice right off the bat; had a good friend help me do some minor adjustments and it definitely helped out, each vehicle is a bit different.

Thanks for are the advice people. I'm thinking about sticking with the stock Quadrajet for now. It's really not that bad. I came across a Torker II single plane model 5001 at a yard sale for 50$. Does anyone know if they are good? I looked up the info when I got home and it says not for trucks?? Why is that?

A single intake is for higher rpm and will not perform well on the street or a daily driver. Your engine is stock and has a very small cam that is designed to have a power range from somewhere around 1000 rpm to 46-4800 rpm. 
The Torker is designed to produce power with a large cam and modified cylinder heads. It is more suited for high performance and racing. A dual plane intake is what you want, such as an Edlebrock Performer, Performer RPM or Air Gap.
