Well today I installed a new 26" 3 core aluminum radiator in the old 69, still had the original 20" 2 core in it and liked to run a little warm with the A/C on (about 3/4 on the temp gauge)..also removed the Magnum fan and clutch, then installed a Chrysler Sebring dual fan set up on it with the typical Bosch power relay hooked to ignition. The radiator was for a 69 A-body small block and fit very well, just had to fab up aluminum angle brackets and drill some holes on the original radiator core support. The biggest pain was the thermostat housing because of the Magnum brackets and pulleys on a 78 360 block with the Edelbrock intake on it made the a/c compressor lay right up against the long Magnum thermostat housing, had to go to the short stamped steel neck. The radiator hose's I used were for a 92 Ramcharger/PU with a 360 Magnum, had to do some trimming but they fit well. Now the truck doesn't even see half on the temp gauge with the A/C on and it was in the 90's today. Took some pics of the finished product and some interior shots of the truck too.
