PPCC List - Serial numbers and vehicle ID

[Steve Goodman V]

Hello Glen: the codes on diff to ID the r/p ratio are very difficult to see
in most cases. If you want to know gear ratio the next time you have plugs
out and a couple of helpers place car in 4th gear and push car I full
revolution of tire while counting how many turns the crank pulley makes.

If just over 3 turns a 3.27
If just at 3 1/2 turns a 3.55
If almost 4 turns a 3.89

Typically a 140hp Corsa is 3.55 from factory but never know after all these
years what it has been changed into.

Plus even if you can read the markings it is no guarantee what someone
could have changed inside.

Enjoy your Corvair!
