ls3 sensor layout i just recently purchased and recieved my ls376/515 carb'd crate engine . being that this is my first chevy engine i am working on . formally an olds motor person and work on my friends ford motors. i am not too sure about which sensors are what.. the ones i do know are the cam and crank sensor . then there is one in the drivers side head i would assume its the water temp sensor? but not too sure . then i have one that is in the back of the intake possibly water but not too sure either . then i have two black sensors on both sides of the block are these the knock sensors. then i have a 3/8 diameter tube that comes off the vally pan under the intake and also a small 1/8 inch tube that goes to both heads in front of the motor that comes out to one tube facing forward.. not too sure about those .. i tried searching on here but didnt have any luck finding it. any help would be apprieciated .. if you need picture i can put them up tomorrow if needed thanks
drivers head----water temp
back of intake-- usually map sensor---since it's carbed i'm not sure
black sensors---- knock sensors
valley pan under intake---pvc
front 2 into 1----coolant crossover---single goes to radiator.
hope this helps
