Build A Brute C6

The C6 Cruise-O-Matic transmission was born to meet the needs of high-torque Ford big-blocks. What makes this transmission such a tough competitor is engineering—a heavy-duty case stuffed full of rough and tumble components that can take extraordinary abuse. Although the C6 can handle just about anything an engine can dish out from the factory, there’s always room for improvement in restoration and performance applications.

We looked to the experts at Premier Performance in Huntington Beach, California, to handle our C6 performance needs. Our subject C6 is from a ’68 Shelby GT500 sporting 428 power. This means it has most of the right stuff for nearly any performance challenge an FE big-block can dish out. We’re going to show you how to take it a step further.
