Our Stage 3 5.2L Long Block is our top-of-the-line assembly for the Audi R8 and Lamborghini Huracan platform. Gone is the stock block, in favor of a Noonan Race Engineering billet block. A more robust rod, piston, and wrist pin assembly is also used in this assembly, given the nature of what will be asked of it. This package carries over our full cylinder head package from the Stage 2, assuring there will be no issues in sustained high-RPM applications. When nothing but the best will do, this is your answer.
