I just got a Cold Case aluminum radiator. They say I need to drill holes in the flange if I try and use an OEM shroud (which I need to buy). Cold Case has a dual electric fan/shroud that bolts up. I have the clutch fan and am going back and forth on which I should use. It's a 340 with 10.5 pistons, mild cam, single 4 barrel. I'm not worried about losing a few HP with the clutch fan, but I wonder HOW MUCH better the cooling would be with the two electric fans? Any advise would be appreciated.
