Important Note: When choosing mounts, ensure they are designed for the specific big-block Chevy engine you're installing (e.g., 454, 427). The dimensions and weight can vary slightly between engine types, influencing the mount design. Check engine block dimensions and compare them to the specifications of any mounts you're considering. You'll also need to factor in the transmission you're using, as that will affect mount placement and requirements.
