Overheating 3208 in a 90SP36

[davidkerryedwards]

It also partly depends on whether you're running synthetic oil or not.
Synthetics can handle higher temperatures. Mike's numbers seem very
low to me. Most aftermarket temperatures guages I've looked at don't
show 'hot' until 240 degrees. I know the idiot light on my 74 Olds is
hooked to a sensor that comes on at 258
