* Find a suitable location and fabricate a mounting point: This would require welding or drilling and tapping a new hole in the block—a potentially risky and irreversible modification. Getting the placement correct for accurate sensing is critical.
* Source a knock sensor and wiring: You'll need a knock sensor appropriate for your engine's application and the necessary wiring harness to connect it to your engine's computer (if you're using an aftermarket computer system capable of knock detection; a stock 1979 system wouldn't have the ability to use this).
In short, while *technically* possible, it's a complex, potentially damaging, and generally impractical undertaking. The effort and cost involved would likely outweigh the benefits unless you are building a highly customized engine management system. It's far easier and more reliable to use other methods for detecting detonation (like listening to the engine's sound), especially on an older engine like a '79 350.
