there was NO orderable "MAX COOLING" on ANY US spec. vehicle (it was part of a "PACKAGE")

the STANDARD cooling system was the same on all A53 "TRANS AM" e-bodies:
2998 974 radiator
2863 216 7-blade fan
2806 070 torque drive unit

the A31 (3.91:1) used a larger capacity "MAX COOLING" radiator 2998 949 with the 340 4bbl (A/C was not available)
