In today’s video, Ken from FST Performance Carburetors shows us how to install and tune an FST Billet X-Treme Series carb on a 1969 Chevrolet Chevelle.

The Chevelle already had an aftermarket overdrive electronic transmission installed, which made the carburetor installation a little unique.

Watch the video to see how to install and tune these high performance FST carburetors, all of which are run on engines at the FST facility and dialed in with adjusted floats right out of the box.

You’ll see in the video that the engine was running a little rich after the initial start up. Ken adjusts the primaries and idle to compensate for an aggressive camshaft, and we’re left with a rumbling Chevelle that pretty much all of us would want to drive.

Check it out.
