PhatNBad Posted August 27, 2014 Share Posted August 27, 2014 Hi folks....I just put a 383 stroker in my 70. The new motor only has a 3/8 npt port in the side of the drivers side head (dart), so my temp (water) sensor wont fit cause its 1/2 npt. Moving it to the intake is not a problem, but Im wondering why the wiring is 2 wires? Seems most of them Ive seen on montes and chevelles is 1 wire. Since I have the original sensor with the 2 flat spade connections, this isn't and issue but Im curious why? Thanks for your input. Quote Link to comment Share on other sites More sharing options...
Toppless72 Posted August 27, 2014 Share Posted August 27, 2014 One wire goes to the gauge; the other is the solenoid power wire for the TCS relay. Quote Link to comment Share on other sites More sharing options...
Sam (Bones) Posted August 28, 2014 Share Posted August 28, 2014 my 70 has 2 sensors, one for the gauge (threaded stud) and a 2 terminal for the TSC solenoid Quote Link to comment Share on other sites More sharing options...
footballubet Posted August 28, 2014 Share Posted August 28, 2014 I'm running the Dart heads also and replaced the stock water temp sensor with a 3/8 npt sensor. Do you need a set of Dart valve covers? I have a set that I had powder coated and looking to sell. Quote Link to comment Share on other sites More sharing options...
PhatNBad Posted September 2, 2014 Author Share Posted September 2, 2014 footballubet - can you send me pics of the valve covers you have? I used the 383 stroker valve covers from summit, but if they get beat up, id love to have a set of dart VC's cause I used a dart intake and heads. What 3/8 water temp sensor did you use? All the research I did says that they're isn't a 3/8 npt sensor that has the right resistance for our cars. Is there? Id love to have one. Im still confused though. The sensor I took out of my stock heads has 2 spade connectors, I dont have another sensor anywhere. So if that one is for the TSC solenoid (which was in the drivers side head) where is my temp sensor? I didnt have a threaded stud sensor anywhere, so I dont have any other wires, just the 2 spades that originally went to the stock sensor. Confused.... If you want to email me pics of the VCs, send them to superChevy@nycap.rr.com. Thanks! Quote Link to comment Share on other sites More sharing options...
