  • 400 small block

    My friend has a built 400 Small Block in his '84 vette and is takin it out, I need to find out if LT1 heads on my T/A will work on a 400 small block. I heard that the water jackets were different, But I was under the impression that it would still work.


    Anyone Know???????????

    I'm 95% sure they are not interchangeable.

      The LT1 is a reverse flow cooling system, making the heads incompatable with standard small block stuff.
