Wound Up

While we're on the topic of cooling, I have used two different fans, two
t-stats and two radiators in an effort to keep my aftermarket A/C-equipped
'67 from running too hot.

Currently, I have a clean 3-row (scale problem wasn't bad) steel rad, the
largest 6-blade thermo clutched fan that would fit the shroud, a 180
thermostat, and recently added one of those cylindrical overflow tanks. The
A/C system is a 1.8 lb. R134 Vintage Air setup. I'll be damned if I can
keep it properly cooled here in Hot Louis. I do run a fairly aggressive
timing curve, and a fairly hot electronic ignition (Pertronix coil and
module). I run it as leanly as is ... well, as I really should, you know.
The little motor doesn't quite get too stanking hot to start, but it does
struggle at times if I'm just running around in the heat. Cruising is fine.
Traffic and stop-and-go blows. When it really gets hot, the A/C actually
becomes counterproductive, if you know what I mean...

So now I am thinking high-capacity electric fan, also to loosen up some
torque, and save a little gas. Advertising doesn't help me. I once read of
a slick elec. fan conversion that flowed something like 1900 cfm in M&F
years ago but I can't remember. Any recommendations?

Thankssss
