I put a rebuilt SB in my 70 about 6 months ago. The motor has been running fine, but I have not driven the car. I had to rebuild the tranny, so I get it back in, and the motor is still running fine. last night I went to back the car out of the garage, and I hear this clanking sound. It initially sounded like a tool droping down and hitting stuff, but now there is a noticeable clank.
Here is the problem now: I can no longer get the motor to idle. I give it a little squirt of gas and it starts and then dies. If I continue to give it gas, it will stay running. (thats when I hear the clank.) Something else that is interesting is that the fuel line seems to be building pressure before it goes in the carb and the #7, #6, #8 header pipes are not hot like the others (at best they are warm). Any suggestions? Could I have a cam or valve problem? What is causing the clanking?
