The 3.9 will give faster acceleration at the expense of higher cruising rpms 
and lower top speed.  The Solex cam and carbs like to work at higher rpms and 
the 3.9 gearing compliments them well.  The 1600 came with a 3.9 so the motor 
will not be turning any more rpms at any given speed than the 1600 would be 
turning.  The overdrive tranny will actually lower the rpms at cruising speed 
relative to the 1600 four speed.  You will definately notice the change from 
the 3.7.

What if one were to put a 3.9 diff in a Solex car? What is the effect? Faster 
acceleration, less topend? Is it a noticeable difference in a Solex car?

Thanks,
