you guys that are running turbo SBC's with FAST XFI . where are you locating your knock sensor on the block ? I have a Dart Little M and was told the best location is "on side of the block between the center cylinders close to the top of the deck. and It's ok if it's in the water jacket" .
2nd question : is FAST XFI designed to take inputs from a mid 80's Spark Knock module from GM, or can it be wired to the knock sensor directly ?
