Default Camaro 73 Carburator Change

Hello guys!
I have recently purchased a Camaro 73. I'm in Bulgaria (Europe) and no one around me seems to have any knowledge on the subject. I want to change my carburator (original) for a new more reliable one. Please give me tips on which option is the best and any tips on parts, installation!
Thank you!

You didn't mention what model and what engine you have but the stock original carb is a reliable unit,you might be best off to get a rebuilt one have yours rebuilt or buy a new OEM replacement.
We can't really recommend a replacement without knowing exactly what you have,there were quite a few different engine options for the 1973 Camaro with different carbs depending on the engine.

I did some digging and I am actually in need of an EFI that would replace my carburator all together. If you can give any tips which one is the best for the car and any extra parts for the installation and tips for the whole change itself as I my dad will be doing it and he does not have much knowledge on old American cars( we are from Europe).
thank you!!!

Well I'm not to sure there's even one available for the inline 6 engine,perhaps Holley makes one.
What do you want to replace the carb? It will be much simpler and less expensive to just replace the carb.

The GM inline 6 cylinder if a very popular motor here in the states. Its slightly bigger brother was put in millions of trucks. I am not sure what you mean by "reliable" In its stock form the 250 (4.1L) was one of GM's most reliable engines. You could buy them for next to nothing because most of the cars that had them and went to the junk yard for reasons other then engine issues. I Drove a 72 myself for 3 years and 80K and never had to mess with the fuel or spark system. Among mechanics the only real known problem is after 100K the distributor would wear their bushing funny because the thing sat on an angle. A carburetor in good condition and getting clean fuel should last at least 10 years. Mine was 13 years old and had 180,000 miles on it when I parted it out to fix another Camaro. I never had to touch the Carb and it was working fine. I just wanted the windshield and the interior for a V8 car.

The only upgrade I would do to a 73 beside rebuilding everything due to age, I would switch to a 1976-1980 HEI distributor. I would replace the bushing and the pickup in the distributor. This would get rid of the points and start a little faster on those cold days because of the increase in power to the plug. You would also want the plugs from those years also

I will agree that stock EFI is great and the aftermarket is good, the aftermarket has some pretty big issues with reliability. I have even seen at shows factory sponsored cars need replacement parts. After market fuel pumps and a lack of people that really know how to work on these system can make for huge headaches. Think about having this system you built on your car and it starts not running right, Then what.

I totally agree here especially about the HEI distributor upgrade.
I've also owned a few Chevy straight six engines and they were nothing if not reliable even the old points fired ignitions which just needed a tune up a little more often.
There's lots of the carbs available online,I'm sure some will ship overseas.
Pretty sure you can get a remanufactured carb with shipping for less than you would pay for a fuel injection set up alone and it would be plug and play,very simple.
