WHY TO BUY?
A new GMC carburetor offers unprecedented reliability in a traditional package, and carburetor manufacturers have continued to develop and refine their products for ease of use and maximum power gains with "out-of-the-box" usability. Of course, carburetors can still be fine-tuned with each manufacturer's proprietary jets, so even though most of today's GMC carburetors are ready to use as they are, you can still squeeze every last bit of power out of your ride with some more testing and tuning.

DID YOU KNOW?
Ever since fuel injection became the norm several years ago, GMC carburetors have become a sort of mystery to many performance enthusiasts. Yes, fuel injection is awesome, but there's something to be said for keeping a classic vehicle true to its roots and embracing the world of float bowls, jets, and vacuum secondaries. Most performance GMC carburetor manufacturers offer both "street" and "race" carburetors, although most street versions can certainly handle the occasional quarter-mile pass.
FAQs
Q: What is a carburetor? Why buy one?
A: Carburetors are mechanical air/fuel delivery systems that were ubiquitous on automobiles before the development of electronic fuel injection. Over the years carburetor designs have been refined and perfected so that now performance carburetors can offer significant performance gains to enhance throttle response, acceleration and top end speed. In addition carburetors are easily tunable by even an average mechanic so that they can be set up for virtually any driving situation from drag racing to road racing. They can also be adjusted to account for things such as altitude or engine displacement. Although relatively simple in design, many people have found that engines setup with the right performance carburetor package can outperform the equivalent motor equipped with fuel injection. If you want to make power the old fashioned way a simple and reliable carburetor is hard to top.
