Talking about how tough those 6 bangers are reminds of the '68 chevy nova i had.I had a rad leak one time,and it was during winter.I had just dropped off a buddies girlfriend,started for home and my idiot light came on.I knew i needed water,but,at 3 in the morning,nothing was open.So, i threw a rag over the light,got on the highway and drove home.By the time i pulled into the driveway,the was knocking and hissing and all round just letting me know it did'nt like the ride.I got up the next morning(afternoon?)topped the rad up with antifreeze,and drove her for another year.Eventually got the rad fixed.Toughest little motor i ever had. thumbs_up
