Stop in for a cup of coffee

Research is something like 190 - 230 ish???? I'd have to go back and verify my source.

Stock I wouldn't think to .. they ran without them for decades.

But, mild build on the engine. Higher stall torque converter and shift kit.... Maybe??
I don't see why it would hurt, into the rad, out to the aftermarket cooler.. i had planned to do that myself honestly.. although i'm sure i would do it backwards cause i'm stupid :)
