[Tigers] More 302 questions

[Bob Hokanson]

I agree with Gary on aluminum flywheels. I've had one in my Tiger for 30+ 
yrs now. The rpms go up and down so quick you need to learn how to shift all 
over again. And you have to be a bit more careful about suddenly lifting the 
throttle in a corner.

I let my son autocross my Tiger when he turned 16. I warned him  about 
lifting in the corners. He lifted, spun the car just missing a light pole 
and flat-spotted my brand new Firestone's. He listens better now that he's 
45.
