<VV> Turbos and 3.27 gearing

[corvair at mts.net]

I had 3.27 in my '63 Spyder coupe (145ci). No problems whatsoever and decent highway mileage was a bonus (28mpg Canadian).

Howdy All, Does anyone have experience with installing 3.27 diff gears vs. the standard 3.55 in 
an EM (1963) Spyder convertible/coupe?  I have to have my differential checked because of a 
persistent whine while running and have the option of changing ratios at this time.  I realize 
that there may be lower highway revs/noise, better gas mileage and that  boost may come on 
earlier because the engine is more "loaded" by the taller gearing.  However I am concerned that 
the car (a convertible) may be even "doggier" off the line than it is now. 

 

Can anyone tell me what has been your real-life driving experience with this setup?  Would you 
recommend the setup to anyone else? Any other considerations or recommendations while doing the 
diff R&R?  Thanks in advance for your thoughts and answers.  Bob Hawley (CORSA WMCC member) -
