Ls3 ported vacuum source Where would I find a timed vacuum source on an LS3 engine. I need a connection for a vacuum switch for a lockup torque converter for a 2004r tranny. I have a rebuilt 2004r tranny from a previous project that I didnt use. Now I want to use it in my new project. I am also using the Lingenfelter 58x to 24x converter that I also already have. Thanks, Scott!

You will find that the lockup kit made by B&M works a lot better than the vacuum controlled type. The B&M kit is speed controlled and adjustable by turning a knod mounted inside the car. I have used both and the speed type is smoother and will stay locked up at part throttle when it needs to. With the vacuum type, every time you come to a SMALL hill, the convertor will unlock, even though it didn't really need to. The speed controlled type is more expensive, but well worth it.
