I have the usual 7-1/2 to 8 quart
oil pan on mine and no
oil cooler and what is probably a too-cool 160 deg thermostat. My coolant runs around 80 C but
oil seldom rises much above 70 C - assuming the gages are correct. And as is, it takes awhile for the oil temp to even get to 70. I just can’t see needing a functional oil cooler in one of these for the street.
