Ron,
First of all have to say the person who advocated drilling any kind of holes
in their stock fan is out of line. This could be a recipe for disaster!
I have the 6-bladed SS fan BCS sells (might be Moss). The hub and rivets in
this fan are very stout, especially since the fan blades are lightweight
compared to the original Queen Mary-style blades. They also sell a spacer
needed to move it closer to the radiator.
I'm also using a beefed Kilmartin fan shroud that fits tight against the
radiator and allows less leakage than the one BCS sells. In addition, I
added a blanking plate across the area between the radiator and front of the
hood opening.
They do make a lot of fan noise. They sound similar to my wife's original
240Z with a stock plastic fan on a hydraulic clutch--I've always thought
these fans have a funky sound--when the car makes more fan noise than
anything else.
I'll bet the plastic fans make the same level of noise.
The solution to this on the Healey is simple--just add a louder exhaust or
rev it up higher in gears :-).
