Thanks indeed for that clarification!
What GM sensor part number, what additional hardware would I need and where would I need to install it if I wanted to add a correctly tuned knock sensor to my 496HO block?

John,
Will the J&S unit work with the Mercruiser "non-resonant frequency" knock sensors (two of them, one on each bank) or is a frequency tuned knock sensor required?

I do not know why I have never seen this thread before. I have distroyed more motors then I care to remember over the years. I had bought the MSD knock sensor but it relied on me watching the lights and while running fast was the last thing I wanted watch.
GPM I know you were running a fast ecm also. Have you done anything with knock sensor's & if so, what did you get and how does it work?

Hi MTI 42, You already have piston sprayers from my fixtures.....These are new motors we have tweaked the design on.....Completely disassembled,changed several components and reassembled.....Bits and pieces of design from Dubui race team,Keith Eickert,Sterling,Zul,ourselves,Boyd Machine and others.....Boyds have done the additional machine work and reassembly.The application focus is on pleasure/poker run that is user friendly,durability and competitive power,in that order....Sanitary aesthetics is a buy product......We have more thoughts to come while looking at the marine industry as a possible business endeavor.........We will be doing a similar process to the next new set of motors,shortly.
Didnt Keith Black make a drill fixture for the piston oilers? Also heard the Nascar guys had it before the marine stuff. I was told it originated from Audi diesel engines.Ya hear so much now days
