Carl-
You saw my yellow GT at the last meet. With a 308 CI Buick, 9.8/ 1
compression, the radiator is larger than stock, but only uses an electric
fan. For many installations, there is not room for a mechanical fan. The
other problem with a mechanical fan is that it runs slow when you are stuck
in traffic & need maximum cooling, and runs very fast at higher speeds when
you do not need cooling, but it does use more HP.

Barrie,
Maybe the aluminum rad had much more capacity. My money is on the mechanical
fan. Most electric fans cannot do what a mechanically driven fan can do,
airflow-wise.
I, also, use a mechanical fan (& a stock MG V8 rad & block huggers). My
stock twin electrics never come on either (okay, except if it is 90+ F & I'm
at a looong line at Hardees, which is much slower than McDonalds).
I could be wrong, but I attribute most of the overheating issues to those
trying to use only electric fans. It can be done with more radiator, a BIG
electric fan, & louvers (and/or fenderwell exit headers).
Anyway, it ain't just the radiator.
