What I did (do), is get a catalog such as Standard Ignition Parts
Catalog.  In there they give module numbers, and interchange
numbers.  On the ecm I used it turns out the were like 3 knock
sensors, and 4 or 5 ESC modules.  Being the lazy, cheap person
that I am,  I took the catalog to a wreckers, and poked around
till I gathered the modules.  $5 a piece. then tried each one to find
the limits of it's detection, and then worked the timing curves
around till no knock triggered, heard, or seen in plug cuts.  
Turns out my v-8 SBC uses a 350 SBC sensor, and a Buick
v-6 ESC Module.  Works fine thankyou very much.
  Same ascoutic footprint?, I don't know.  Do I care?, no.  Bottom line
is that it works as it should.
Cheers
