Re: Another fuel economy check with my '65 one ton
What do you mean? I agree that vacuum leaks are a potential issue, as they are with anything else (although the intake/exhaust manifold design probably doesn't help things), but the sixes pull plenty of idle vacuum when they are running like they should be. It's not like they came with radical cams or anything.
