Another way to think of it is: the heat we are asking the cooling system to dissipate is proportional to (and is a byproduct of) the heat made by the motor when it does "work" (pushes the vehicle and its payload). There is probably a significant difference between pushing a three-thousand pound Mustang up to freeway-speed with a 450-HP motor than a fifteen-thousand+ pound Deuce up the Cajon-pass with a multi. That said, the typical military "worst-case/overkill" spec probably has a fair amount of "cushion" in it (probably allows for bullet-holes through a third of the tubes or something); so I'd love to hear you find out the Mustang radiator works OK. If you can: find out the specs on that fan too. The fan's CFM-rating is going to be more important in the Deuce because of its lower average vehicle speed - the radiator gets more airflow than most fans provide above about 40-45 MPH of vehicle speed, but the Deuce spends the majority of its time below that threshold (mine does anyway). Just my 2-cents.
