If you are talking core sur= face area the oil cooler is approx 19x4 =3D 76 sq inch.  so 3 times that = would be 228 sq inch.  Two
of the GM evaporator cores will give you 95x2 =3D 190 sq inches so the area s= ounds OK.  How about the core volumn? Yes, thickness does play a part i= n cooling.  The two gm cores have a core volumn of 2x( 9x10x3.5) =3D 630 = cubic inches. Just for a point of reference.


Ed,
The oil cooler has 2” thick core so, 76 sq inches x 2 =3D152 cubic inch= es.  Rad. will be 152 x 3=3D458cubic inches.
