The 1977 Corvette was designed for smaller-block engines, such as the 350 and 400 cubic inch V8s. Installing a larger engine will require modifications to the engine compartment, including cutting and welding to fit the larger engine and its components. Additionally, the larger engine will change the weight distribution of the car, potentially impacting its handling and performance.
The transmission, driveshaft, and rear end of the 1977 Corvette would also need to be upgraded to handle the increased torque of the big-block engine. This may involve replacing the transmission, driveshaft, and rear end entirely, or modifying them to make them compatible with the bigger engine.
While it is possible to install a big block engine in a 1977 Corvette, it is generally not a straightforward process and requires significant expertise, fabrication skills, and potentially specialized parts and components. It is recommended to consult with automotive professionals who have experience in such engine swaps for accurate guidance and to determine the feasibility and cost of the project.
