Most vehicles I owned will allow me to put my hand on the oil pan if I stop as soon as the coolant is up to operating temperature on a cold day.
There are at least a few posts on here talking about oil to coolant warm up times on exchanger less systems.
On a vehicle that does not have a heat exchanger or cooler the oil can get hotter than the coolant by up to 20°F, but it takes a while.
I'm putting together a 454 bored and stroked out to 489 with 11:1 compression. Instead of running expensive fuel all the time I am going to try to run regular unleaded and then have cheap water methanol kick in when I get on the throttle.
