Let's simplify the expression step by step:

The expression is:

\[ 7 \times 64 + 57 \times 37 \times 11 - 600 - 277 \times 64 + 57 \times 37 \times 11 - 600 - 27 \]

1. Calculate \( 7 \times 64 \):
\[ 7 \times 64 = 448 \]

2. Calculate \( 57 \times 37 \times 11 \):
\[
57 \times 37 = 2109 \\
2109 \times 11 = 23299
\]

3. Now input this value into the expression:
\[ 448 + 23299 - 600 - 277 \times 64 + 23299 - 600 - 27 \]

4. Calculate \( 277 \times 64 \):
\[ 277 \times 64 = 17728 \]

5. Substitute this back into the expression:
\[ 448 + 23299 - 600 - 17728 + 23299 - 600 - 27 \]

6. Now, simplify the expression step by step:
\[
448 + 23299 + 23299 - 600 - 600 - 17728 - 27
\]

7. Combine the constants step by step:
- First, sum \( 448 + 23299 + 23299 \):
\[
448 + 23299 + 23299 = 448 + 46598 = 47046
\]

- Now, subtract \( 600 \) twice and \( 17728 \):
\[
47046 - 600 - 600 - 17728 = 47046 - 1200 - 17728
\]
\[
47046 - 1200 = 45846
\]
\[
45846 - 17728 = 28118
\]

- Lastly, subtract \( 27 \):
\[
28118 - 27 = 28091
\]

Thus, the final result of the expression is:

\[
\boxed{28091}
\]
