How do you make a 1986 box caprice fast with 26's in rims?

To make a 1986 Chevy Caprice faster while using 26-inch rims, you should start by upgrading the engine for better performance, such as installing a high-performance intake and exhaust system, and possibly a larger carburetor. Consider adding a performance camshaft and tuning the engine to optimize power output. Additionally, upgrading the suspension and brakes will help manage the added weight and improve handling. Finally, using lightweight components and optimizing tire selection can enhance acceleration despite the larger rims.
