Advanced Engine Design - 5585 - TUNING KT QUICK CHANGE

Vacuum secondary carburetors are designed for universal installation on varying engine sizes and power levels. In turn great improvements can be made by tailoring secondary opening rates to specific engine combinations. We have seen as much as 35 Feet Pounds of torque increase on a 355 CID engine when combined with our machined throttle plates and high flow screws. We offer a complete spring kit and a kit that contains a sprint kit plus a quick change removable vacuum housing that facilitates thirty second spring changes. Our Metering Block Conversion Kits are designed to convert carburetors to style with the addition of new metering blocks and hardware kits that provide you with the means to effectively tune the secondary side of the carburetor over the nonadjustable jet plates. Includes all components necessary except main jets. Finally a fully adjustable secondary jet plate. Now you can tune your vacuum secondary carburetor without buying multiple jet plates. Just remove the bowl and change jets like a conventional metering block. The advantage is you can use all your existing components like fuel lines and bowl screws and not increase the length of your carburetor. Great for multiple carb applications where carb length is a problem
