Best bet is to use the sending unit that matches the factory gauges. As you found out with your other swap it might need an adapter. I am running a LSX block in my 71 with a Stewart water pump for Wegner - fortunately the water pump is SAE and I used the original sending unit that was in the original 307 many moons ago.

Are you keeping the factory fuel injection? If so, someone should be able to hook up a computer to compare what the computer is reading vs. your factory gauge, good insurance that everything is correct.
