I have my first vett it is a white 1979 t-top some hi-miles on it but the price was right. It has a auto 3 speed I have not found out what type of rear end it has in it yet, but to do 70 MPH I am at 3,200 RPM on the tack. Read alot of things on this in the last few days, don't know what I will do leave it or do something about it. Love all the C3 photo's on this page. HIGH and BY.
