It says not to be used with hydraulic roller camshaft vehicles because they have different timing gears. Also it isn’t a good idea to use this on a fuel injected SBC because it can and most like will set of the factory knock sensor and pull timing like crazy. It will sound cool and perform like shit ---

[quote=“BrockwayMT,post:3,topic:27607"”] got to buy the lt4 knock sensor if you’re going to use them noisy drives [/quote] That won’t even do it… Depending on what motor you are putting it on; if it’s an LT1/LT4 motor, then you have to modify the timing cover for it to fit; program out the knock sensor completely, and run an electric waterpump. Plus there’s one for hydraulic cam motors I believe. ---
