Question...what is the normal running temp for a 1972 340

Everything is original as far as the air flow through the grill with the exception of a trans cooler which is a radiator looking cooler that lets air flow through it also and only covers 12'' x maybe 10" of radiator ....... and that sets 6" in front of radiator allowing air to flow between the two ......also had this issue before trans cooler. other than that is open. Also it does have a 7 blade fan .....
