Most variable valve timing systems, like the one found on the new Chevrolet LT1 engine, only offer provisions for retarding a camshaft – there’s nothing that can be done to advance the camshaft. Livernois Motorsports has developed a unique solution with their new Total Control Cam Timing Control System. Available for the aforementioned LT1 along with the Three-Valve Modular Ford 4.6, the GM LS, and the Mopar HEMI engines, the system provides a way for the user to set the camshaft where it needs to be for optimum performance.
Through the use of an offset vane that provides the user with up to six degrees of camshaft adjustment, and a set of phaser limiters that are included in the kit, the system retains the rest of the stock parts for simplicity’s sake.
“Let’s say the cam comes in at 114 degrees, and you want to advance it, you’re out of luck. By using the offset vane, you can adjust it from 114 to 110 degrees easily. We’ve found a lot of variation in camshaft cores, so you’re almost stuck with using this to get the timing correct,” says Livernois’ Dan Millen. The kit provides for adjustment in one-degree increments up to the six-degree max.
Millen says the kit was initially designed for the LT1, as there was a need for it in the company’s shop on their customer vehicles, and they subsequently developed it for the other engine platforms.
