I have a Chrysler 400 from a 1973 Plymouth Satellite in my 70 duster. I bought the car with the engine already in it.
While testing the other day I noticed that the temp was about 200-215 on the top of the heads. About 145 at the TOP of the radiator at the hose and about 194 at the BOTTOM of the radiator at the hose. All was done with my temp gun. The car has a sending unit in the stock location and it reads about 20 degree higher than the one in the radiator itself.
question : if the flow is normally bottom to top, this doesn't add up. I believe I am using a stock pump housing and a high flow standard rotation pump.
should temps be lower at the bottom of the radiator?
