GPI MAX Performance Head / Cam Package on the Engine Dyno
THE ENGINE DYNO RESULTS ARE IN! 150HP MORE THAN STOCK LS3! Here is our latest testing of the LS3 / L99 MAX Performance Head & Cam Package. We've taken the goodness of the LS7, and adapted it to the LS3 / L99 platforms, to create a package that is the best of both worlds! The MAX Performance Package is built with an LS7 Cylinder Head, which lets us run a smaller combustion chamber, with additional piston to valve clearance, and still run a lot of camshaft. This seems to be the perfect combination. https://gwatneyperformance.com/produc...
