Has anyone tuned their 4 speed cam with a vacuum gauge. Set the timing at maximum vacuum readjust the idle mixture and speed, and see how it starts and runs. You guys that have 4 speed cams, when you installed them, did you degree them in? Was the cam ground with advance built in?
Thanks Toolmanmike, I will look into adjusting. I just set the timing to TDC as the book says. The car runs well, it just shows a low VAC. Everything else is a NO, unless the purple DC cam already has it added in.
