Bill, what have you got against Tony? His is a real world example of the 
cars we drive. Not everyone has factory fresh Corvairs at their disposal 
to mix and match factory fresh parts. Does not Tony's 110 164 cu in  
engine have the higher torque you speak of? Is it not mated to a 1960 
PG? Just try to get an earlier Corvair PG to experiment with! Is the 
transmission not performing just as well now as when the engine was 

Just remember the original question: "Has anyone used an early model PG 
with a 164 engine?" Tony has, and with no documented troubles.

If you want to do an engineering paper on problems using an early PG 
with a 164 cu in engine, I suggest you do not ask here, but invest in 
new parts to do a proper engineering test. The rest of us in the real 
world will still use used parts and drive our cars, swapping stories of 
swapping parts not approved by GM.
