Big block cooling question

Good deal, thats what I run 1 1/4 cores, 2 rows Griffin I have no cooling issues even with factory A/C. Went for a 30 mile ride yesterday 92 degrees and hi humidity, never got above 180 degree F.
You have the capacity to cool it can only be 2 things not enough air and/or not enough flow.
It is not rocket surgery but sure can be frustrating and expensive.
Good Luck
28x19 instead of 18. I took it out for a short trip to town to fill it up today. The temp was 96, with 57 % humidity, heat index was well over a hundred. Engine warmed up to about 190 and held till I got to the first stop light, went to 202, thru town, topped tank off w/ real 91, temp went to 215, dropped to 212 and stayed there till I got back on the 4 lane, dropped to 206, till I started wasting a smart ***, went up to 208 till I got home. Not bad, but seems like the car runs better around 190 -195.
Still going to try a a clutch fan next, will have a bunch of fans for sale when I get done testing.
Thinking about a flowkooler water pump to, just don`t know if it will be bettr than
the hi volume that's already on there. My 15" pusher in front will run my battery down also. Tempted to take it off and try it w/o it , according to stansblu72 `s suggestion.------------------------AND THE SAGA CONTINUES----------
