I know that the carburetor on this 75vette i bought needs to be rebuilt, but what i am also wondering if it is a very good carb and if i should upgrade it to something beefier.  here are some pics!

That's an Edlebrock "copy" of the old Carter AFB carb. They're pretty good carbs, for the most part, and fairly easy to set-up/tune, compared to Holleys.

any idea as to where i can find a rebuild kit for that carb?

Any parts house should have them...those carbs are pretty popular. Napa, PepGurls, AutoZone, etc.....
There is a series of numbers on the base, lower passenger side. Write those numbers down and call your local parts place, and see if they have the kit in stock.

So i'm half intimidated after looking up the parts number and the info for this carb (thanks for telling me where to find the number) i am wondering if i should really attempt to try to rebuild it myself with a kit or have a mechanic rebuild it for me, it is an Edelbrock 1407 carb and its been something like 3 years since this car has really been run well.  I have the time to do it but i don't know if i have the expertise...  i sadly feel like i'm lacking more and more of that each day that own this car...

Jon, I'd tend to concur with you on carbs - most of the time in the past when I've messed with 'em it hasn't turned out well.  BUT - good news here - I've recently had a pretty good experience rebuilding an Edelbrock copy of a Q-jet, the OEM carb for our cars.  (Edelbrock is good at copying already good designs).  My recommendation if you build it yourself: get yourself a really good, recommended book for the Edelbrock/Carter AFB and follow it closely.  Don't skimp on recommended procedures and cleaning, if you don't have the required tools, buy 'em or borrow 'em, don't try to make do, and just go really slow and spend some time.  The internet (including this site) is also a valuable tool.  

I have much the same Edelbrock on my '75 except mine is the 1411 which has an electric choke. I've had good luck with it. I'd have rather had the 1426 650 cfm though as I think the 750 cfm is too big.

Edelbrock square bore carbs are a fairly simple design. Like Adam said its a copy of the old Carter AFB carb. I had one years ago on my '79 Chevy K10. They are simple to rebuild. I had to open up mine to install the offroad springs for the floats. Once I did that I never had to mess with it again.

Rochester Q-jets are also a very good and much maligned carb as mentioned by "daveo76." I've been running a Q-jet on my vette for years with no real issues. I did try the Q-Jet made by Edelbrock when they first came out. It was much better than the Holley Street Avenger I tried. The only problem with a Edelbrock Q-Jet is that they use truck metering rods. Truck metering rods will cause a lean condition at wide open throttle at high rpms. Not good for pistons. I found this out when my Air/Fuel ratio went super lean during a dyno run. Also spoke with a guy named Lar's who was the carb guru on the other forums. He informed me of the truck rods in Edelbrock Q-Jets.

Not trying to take away from the info "daveo76" posted but merely add another option.
I had SMI "Sean Murphy Induction" www.smicarburetor.com build me a Q-jet specific for my car. He was very thorough wanting to know various details about the car to set it up correctly. They did an awesome job. Car runs strong with no issues.

Good luck!

Welcome to the group, Jon.  Feel free to ask as many questions as you can think of, lots of help here!!!

Thanks Dan!  and yeah i will be asking LOTS of questions! i have alot of issues to work out with this vette!  on the bright side i managed to do a great job of getting that carb rebuilt! thanks everyone!
