Product Description

LS7 Cylinder Heads To LS3 SC Intake Manifold Billet Adapter Kit | Tall
This pair of adapters allow the use of LS7 style cylinder heads on a L92, LS3, LSA, LS9, and L76 style intake manifold when used on a tall deck block application. This will allow the use of a supercharger that is only manufactured in a L92 design to be used with high flowing LS7 heads.

Overview
These precision-engineered billet adapters are crafted to bridge the gap between the LS7 head and the intake manifolds designed for L92-style engines. These adapter plates effectively modify the intake port geometry, allowing the use of L92, LS3, LSA, LS9 and L76 intake manifolds – and therefore, their corresponding supercharger systems – on LS7 heads mounted to a tall deck block.
The significance of these adapters extends far beyond a simple compatibility fix. They open the door to a previously unattainable performance combination: LS7 heads, a tall deck block, and the wide selection of superchargers designed around the L92 manifold flange.

Why Choose these Adapters?
Forced Induction Options
Easily integrate common L92/LS3/LSA/LS9 supercharger systems, which are often more readily available and have better aftermarket support than dedicated LS7 superchargers.
Tall Deck Compatibility
Overcomes the challenges of utilizing LS7 heads on a tall deck block, giving you the foundation for massive displacement and power.
Performance Gains
This combination allows for a potentially dramatic increase in horsepower and torque, especially when paired with an aggressive tune.
Considerations:
- While these adapters facilitate the installation, remember that you may need to adjust other factors in your setup (tuning, etc.) to optimize the performance of the LS3 intake on your LS7 heads.
- Always double-check the fitment of all components during installation to ensure a proper seal and avoid any potential issues.
