Temp Sending Unit

Hey guys I just got my short block back from the engine rebuilder and I also got a set of fresh heads and I am getting ready to assemble the heads to the block. The car was originally a 1977 L-48 and I am trying to figure out which side of the engine that the head with the hole for the temperature sending unit goes on. I honestly have no idea because I bought the car as a fixer-upper with no engine and I bought everything pieces from the machine shop. Need help soon. Thanks

Almost all small block Chevy engines have the temp sending unit on the drivers side between #1 and #3 cylinders. Look for a green wire with a single female plug to hook to it.
