I have a 70 Barracuda I bought a few weeks ago. It has a 340 with a 727 trans. I want to add an electric fan and in the future EFI. I noticed there isn't any where to add the temp sensors. There is only the stock temp sending unit on the intake manifold. Is there some where on the engine block I can use? Anyone have any recommendations?

Buy a sending unit for an electric fan, then splice the wires or add a connector to run your temp gauge.
If you buy a new fan set up it will likely have a sender included; these usually are temp rated. Also, you should definitely run the fan(s) off a relay(s). The wiring is super simple for a four pin relay.
