572 Running hot or just the gauge?
So here is the deal. Finally got the car back together for the 5th or 6th time now chasing coolant and oil leak issues - hoping the end is in sight soon as this is getting very tiring. Anyway, took a test ride yesterday. Was around 91 degrees out so it was a hot day. Driving at normal speeds car was running around 195. At a stop light 210. Driving again would eventually get down to around 200ish. Stop light again just the width of the needle over 210. Being it is an electric gauge, I shot it with a $20 laser temp gun to double check. Everywhere I shot I couldn't anything close to 210 unless it was on the head down my the headers. Headers read 230 at the highest temp but they are a polished coating too. Took readings on the top of the rad(polished alum so I figured not accurate)150, Thermostat(polished again)155, under the housing 185, heater hose fitting in top of manifold 185, temp sender in manifold 185. Front of heads 195........Question is where exactly is the best place to get the most accurate temp? I am 90% convinced my gauge is wrong, but need confirmation.
