  • Buick 455

    I can't tell from doing research if this engine is the same as the Olds or not. Some things I read say yes, some say no. Are there any significant differences? I'm putting one in my 85 Salon and want to know if I'm headed for trouble.

    Buick, Olds, and Pontiac 455's are all different engines. Accessory brackets are different. Transmission bellhousing patterns are the same.

      Does that mean the holes in the heads for the brackets are different? They look the same to me but I haven't looked closely. What about the overall dimensions? The front cover on the Buick is longer because of the front distributor. Will it fit? What about the engine mounts?

        Everything is different except the bellhousing mount as far as I know.
        The mounts look the same but the location and frame pad is different...

          Fabbing mounts and brackets I can handle but I sure don't wanna go cutting into my AC box. Block is already at the machine shop...

          Thanks for the info guys.
