Hey y'all, guy I know is about to put FI on his big block, in his 55 Chevy. He needs to put a knock sensor in the block, but apparently the water passage he was going to put it in, he rounded off the plug. He doesnt wanna dissasemble the motor to get metal shavings out of the water passages if he were to drill it out. He has the plug under the fuel pump blockoff plate(since hes gotta go to a electric pump). Will the knock sensor work in that oil passage, or is the oil too heavy to transmit pings to the sensor? Thanks guys, Im not sure on this one, Ive always seen em in water passages, never oil. Chris.
