 The cars never came with a fan shroud; they were add-ons for mostly the engines after the '73s, which had about 2 extra quarts of oil to help with the cooling. As noomg stated, the
3 row radiators with STAGGERED tubes(i/e., not in line with one another) work well.
Many have gone to a CHAMPION aluminum radiator(about $220 on AMAZON) which will take care.
BUT--BE VERY CAREFUL; THE '75 AND LATER ENGINES WITH THE WIDE CLUTCH FAN WILL TOUCH THE BOTTOM OF THE CHAMPION ONES(they're a bit wider) AND RUIN ITUNDER HIGH RPMs. THE BOTTOM BLADES WILL FLEX OUT.
found this out the hard way and ordered another CHAMPION but put the smaller yellow fan on.
I've got a bunch of fan shrouds; we were, up until the early 2000s, able to get them 4 rowed, but no longer.
