Car Craft – October 2019

The Billet X-treme is intended for the

upscale enthusiast looking for pure race

adjustability. This mechanical-secondary

750 unit features multiple opportunities.

The main body, float bowls, and metering

blocks are billet aluminum. Note how

the baseplate offers a dual pattern to

bolt to standard as well as 4500-style

mounting flanges.

Even the simplest of the Fuel Systems

Technology (FST) offerings like this

650-cfm RT vacuum-secondary version

uses what FST calls a pressure-based

casting that offers an exceptionally clean

appearance. This version is a single-inlet

carb with a metering plate instead of the

more performance-oriented metering

block with changeable jets.

This tight view of the Billet X-treme reveals an interesting option that can include

a throttle position sensor. This makes it easy to convert to an electronic-feedback

transmission like a 4L65E or 4L80E automatic. Also note the four-corner idle capability.

Below: We disassembled this

FST Billet X-treme 750 to

reveal the primary metering

block and float bowl, and its

conventional configuration

for the metering block,

power valve, and main jets.
