<VV> 8 plate oil cooler side shield question

[Sethracer at aol.com]

That is, of course, why we actually run the horse race! I have heard the  
argument on both sides of the folded fin vs. the 12 plate cooler many times. 
If  both are brand new, or at least spotlessly clean, they probably have 
about the  same cooling capacity. But I can tell you, having opened up dozens 
of Corvair  motors and unearthed the oil coolers, the 12 plate still retains 
its cooling  capacity and many - if not most - folded fins are way below 
their capacity  because of the tiny passages which get clogged up. If you 
promise to keep your  engine nice and clean (and that is why Chevy installed that 
removable cover) and  your engine is already equipped with an 8-plate, 
12-plate or a folded fin  unit, just clean it up and motor on. I would not go 
from a good 12-plate to a  folded fin (but maybe from an 8-plate). It would 
involve air-plumbing changes  too. If you have any of the plate-type coolers 
off, go ahead and add the side  shields when you re-install it. GM thought 
enough of them to put them on the A/C  cars. - Seth Emerson

The  FF cooler was used on all 1962 Corvairs.  

Starting in 1963 the  plate-type cooler was used on all Corvairs. The 12  
Plate cooler is  superior to the FF cooler in several ways:  Less  
restrictive 
to  airflow. Better oil cooling at high speeds and less likely to  plug-up  
with dirt/dust, etc.

Is it  better (more  effective) than the 12-plate? Did the early 62-63, and 
64 turbos  use  it?
Just curious.
