To simplify the expression \((14^3 \cdot 27^{-7})^{0/3^4}\), we start by simplifying \(0/3^4\).
Since \(0/3^4 = 0\), we can use the property of exponents that says any number (except zero) raised to the power of 0 is equal to 1. Consequently, we have:
\[ (14^3 \cdot 27^{-7})^{0/3^4} = (14^3 \cdot 27^{-7})^0 = 1 \]
Now, \(1\) can be expressed as a simplified fraction with no remaining exponents:
\[ 1 = \frac{1}{1} \]
Thus, the final answer is:
\[ \boxed{1} \]
