67 Running Hot...Still
I've had the car a year, motor was rebuilt a few years ago, before I got it. It's a 67 289 block with 72' 302 heads. It ran hot when I got it. Here's what I've done to it since. New Auto meter gauges, new sending units, new Edelbrock Performer 289 intake, Rebuilt the Edelbrock 600 Carb, Rebuilt the C4, new front suspension, new pads, rotors on front, new brake booster, new master cylinder, new water pump, new thermostat ( I think it's a 160), new 3 core radiator, new heater and box, new fuel pump, new fuel tank, new front seats, etc.
Now that I have real gauges, it's running about 235, even on the highway, it's not a stop light heat up. It just seems to start running hot as hell. The radiator seems to flow. It has the Duraspark ignition, which was already on it. I've had a few electrical issues and started using relays. All the wires for the gauges are new with the exception of the backlights, I used the original instrument panel light wires to keep the ability to dim. I had some twitching on the tach when emergency flashers were on or blinkers. I've read that low voltage to the coil can cause an overheating. Is this a possibility or is it the thermostat should be 190? Any help would be appreciated.
