Rochester 2GC 2-Barrel Carburetor for Chevy 350 5.7L & 400 6.6L V8 - LARGE BASE ONLY (3 11/16" x 2 1/16") - Hot Air Choke - 1970-1980 C10 K10 Impala Chevelle GMC Pickup

Installed and worked like a charm on a 1976 El Camino V8 5.7 350. Same fit, no leakage, great value for the money. I saved over $250 in parts by installing instead of rebuilding the old beat up carburetor which was giving me grief. You just have to tweak it once installed but Youtube helped with that. The plus of this carburetor is apparently the parts can handle ethanol. Highly recommended so far.

Worked great on my 87 Chevy v8 350 small block. Bolted it on and adjusted the idle and never had a problem. Been working on my truck perfectly for 2 years

Seemed to work well after install, but tried starting second day and locked down motor with piston full of fuel. One piston fired before gas filled piston locked down. Motor has bent rod and crank now. Tried saving a few bucks ordering this one and now I'm looking at a whole motor build again. Only had about 10k on motor at time. Won't know full extent of damage until full breakdown. I've received a replacement carb but now only have blown motor to put it on. LOTS of work ahead of me now.

This 2 barrel carburetor worked on my 1962 StudeBaker gt hawk. Had to use a adapter plate but I did not have to male no adjustments. Fired right up no gas in the carburetor and no adjustments needed . I would highly recommend this carburetor and this seller.

Carb seems to be well built and function properly. However, this is not built to be used interchangeably. If I was to guess this carb is set up for a 220-250ci engine. The main jet size is a 54 and the jets are a small metric thread, so a standard jet kit will not work. I was able to drill out the jets as well as the air bleeds to get the carb to operate/respond properly under load. Would not suggest modifying carburetor unless you know what you are doing!

Works fine for low key driving. Accelerator pump didn't work right from the beginning but it was the only problem for quite awhile so could ignore it. Until it developed a vacuum leak in the gasket between the plenum section and throttle plate. Since this was a few months past warranty I decided to fix the accelerator pump at the same time. Opened it up to find the pump is not a normal Rochester size. I had to special order a 13/16" cup for a Mercarb instead. All things considering I'm giving only three stars because breaking down with the vacuum leak after only putting 200+ miles on it was disappointing.

I did some drilling to attach my throttle linkage and 700 R4 throttle valve cable. My 65 el Camino originally had a power glide. The intake manifold and Carburetor is off of a 71 elcamino. This carburetor comes with a base gasket, which is a rectangle flange with only two holes drilled into the gasket just like the original carburetor head. I went ahead and carefully drilled out the other two holes into the gasket. So now I have four studs holding the carburetor down. This is not necessary, but for me, I think it's the right thing to do. Also the choke thermostat on this carburetor uses a metal line, going into the intake manifold, and then attaching to the rear of the carburetor. My manifold had the thermostat on the intake manifold, which is different than the carburetor mounted thermostat spring. . I just put a pull spring on the choke linkage and to hold it open all the time. I can see where this carburetor fits different applications and I think it's a good choice. I have no issues. No leaks no problems. Everything is great.

I was getting 9mpg with a 4bbl Edelbrock on a mild 350, pit this carb on and it fired right up out of the box. No adjustment needed, I ran it on a 300 mile trip and averaged 17mpg and it ran much better with the 2bbl carb. Make sure to use two fuel filters and it will be good to go!

Good packing, well built, fire up and ran right out of the box, small adjustment to choke pull off and idle mixture. Good value.

No cabe, queda muy poco espacio entre el carburador y el cofre en un malibu 81

It looks very nice but there a problem with the idle circuit. Hopefully I can find the issue or it just become a paper weight

Easy to install
