<VV> 102 HP FC Engine

[RoboMan91324 at aol.com]

Gary,
 
The VD engine (and the PG version) is indeed rare and for a  good reason.  
GM stopped installing them very soon after they started  replacing them in 
the field under warranty.  An FC is the worst  possible application for a 102 
HP motor.  Of course, it is OK for use in  cars, depending on differential 
ratios, etc.  The reason that the 102 is OK  for a car and not an FC is that 
it has the highest compression ratio of any  Corvair engine and the power 
band kicks in at a quite high RPM.  The FC  weighs more than the car 
especially when loaded and it has terrible aerodynamics  compared to the cars.  
Because the FC needs its torque at lower RPM, the  102 will "knock" itself to 
death before it gets to an RPM where it is  comfortable.  Further, in a car, 
you can usually hear the knocking and  react to it.  In an FC, the engine 
knocking usually is not heard and  continues 'til death does it part.  This is 
especially the case with  Rampsides.
 
So, 102 HP engines are rare because GM realized they were not  appropriate 
for the FC and many of the 102's that made it into the FCs self  destructed.
 
If you have a 102 HP FC engine it is valuable simply because  it is an FC 
engine.  How many of us have car engines in our FCs?  If  you have one of 
these engines and want to use it, I would strongly suggest that  you use lower 
compression heads and possibly a less radical camshaft and  distributor.
 
I have a VD engine and will turn it into a 110 HP 164 CI  engine before 
installing it into one of my FCs.

Bob to my understanding the WC engine  was a wagon engine and that FC 
engines were coded with a V. If I am wrong I  hope someone will inform me, I have 
been wrong before. I believe the V engines  came with valve rotators and 
the W engines did not. There may have been other  differences. I have a 1963 
VD 102 FC engine near KC MO, I think there is  another one available in Iowa. 
They are a bit rare, Clarks does not list the  ID code.?GMoore
