<VV> regular gas and fuel economy in a 110hp corvair

[Dennis Dorogi]

I meant to put .042 copper head gaskets in my 110 hp powerglide 4 door that 
pinged rather badly.  By mistake I ordered .052 gaskets but since I wanted 
to get the car on the road I put them in anyhow.  Result?  Maybe I lost some 
horsepower - I don't miss it, but I use 87 octane and can hardly get it to 
ping even in 95 degree weather.   I have been driving it that way for about 
10 years now.  Just my experience.   Dennis Dorogi
