Thanks for the quick reply.
The guy selling it is a mechanic, he is the one who installed the new motor and trans. I saw this car at the Service Station where he works. I have long taken my cars there for service, and have always been satisfied. He is currently installing a new carb in my Camaro Z28. Should I trust him with this, or have another mechanic check it out. I am so unsure, and afraid to lay down what to me is a big chunk of change.
