Snowman,
Just a FYI,
my friend is a distributer & friends with the owner for the J&S safe guard units.


He has built many high performance engines & has installed many J&S safe guard systems w/ knock sensors on many builds. They work great.

A knock sensor will save your engine, something you need since this will be your 3rd engine due to detonation you cannot hear & a knock sensor can.
