FWIW our filled block has been together and in the car since 2001 and never had any issues. I run an oil cooler for insurance, never have seen oil temps over 230-240 and that is only after sustained highway jaunts. Car make 750+ HP fwiw as well and we never ran it without the cooler either. Saw no need wanted it just to make sure.
Spot on AL. This is exactly where I am with my street 528 Cuda, as you say sustained highway use get the temp up. I often wonder how many people are out there without a oil temp gauge ??
Dave If you don't run a cooler with all that fill your first 1/2 hour drive will see 300 on the oil temp.
