Hello all. I've got a siily question but I'm going to ask it anyway. Is the 195 degree t-stat the correct unit to use on my '73 340 engine? It's a '73 engine in my '70 swinger. It warms up to OK 195 degrees, then when I get it out on the road cruising, it creeps up 205, then up to 210 sometimes but hovers around 205. It just seems a little bit too warm, or is it? Should I go with a 180 degree or leave it alone? It doesn't overheat, not yet anyway, and the car has an electric cooling fan as well, just in case. Any thoughts? Thanks, Steve.
