Aluminum 289; 364CI Stage I (500HP)

We have modernized one of the most popular engines of all time, the 289. All of our 289 engines start with our Aluminum 289 block. Cast in California, these blocks are stronger and lighter then the original cast iron blocks. They are a direct replacement for original iron 289 and 302 engines. Very popular for the Shelby CSX7000 Cobra, CSX8000 Cobra, and Shelby Daytona Coupes. These powerful small blocks are also a perfect fit for any restomod project

Each of our complete engines are numbered with a Shelby CSX number and includes the option to match numbers with your Shelby Cobra CSX number.
