What would it take to swap out an Oldsmobile 260 for a Chevy 350?

Swapping an Oldsmobile 260 for a Chevy 350 requires several key components: a compatible engine mount kit, a new transmission or an adapter to fit the existing one, and modifications to the exhaust system. You'll also need to consider the fuel system, including the carburetor or fuel injection setup, and ensure that the electrical wiring is compatible. Additionally, alterations to the cooling system may be necessary to accommodate the new engine's size and requirements. Overall, this swap involves mechanical know-how and possibly custom fabrication.
