Gain plenum volume, improve cylinder balance, and make your Hi ram manifold look better! We offer these tops in 3 different heights. Our standard tall model is 6.5", the mid height is 5", and the low profile comes in at only 2.75". These all include a vacuum block on the rear that feature two 1/8" npt and one 3/8" npt female ports.
These are built once the order placed.
When choosing the throttle body style you are choosing what throttle body you currently have. YOU ARE NOT CHOOSING WHAT FLANGE GOES ON THE TOP. Please contact us with any questions you may have.
If you would like a throttle body bracket added to your top please purchase separately through the website.
If these tops do not fit your project we can make a custom top for $575.00. Contact us for more information.
