My 351W normally runs between 88 and 95 deg C water temp with electric fan always on--except for when I'm on the freeway for more than a couple of minutes.
I put in a slightly larger all-aluminum radiator and changed to a single 16 in fan with shroud because I had observed coolant temps of 100+ deg C on a few occasions. 95 deg C is pretty much the max that I see now.
My
oil temp has reached a maximum of 85 deg C during extended stop and go driving. Any airflow cools it right down to about 70 deg C. (Canton road race pan and 8 qts).
Cheers
