    '70 B Body Steering Column Question

    Please take a look at the attached photo; What is the purpose of the flange on the steering column? It's silver in this picture. I'm assuming it's part of the shift linkage on a column shift automatic car. But what purpose would it serve on a four speed manual car and why would a four speed...

    My 440 was rebuilt .030 over to stock specs except for a mild cam 30 years and 25,000 miles ago. (It was rebuilt by a previous owner.) I unscrewed the oil sending unit and screwed in my shop gauge. I'm getting a tick over 50 PSI at cold idle, it drops to a tick over 20 PSI at hot idle. It's...

    440/6 Power Valve Question

    My '70 Plymouth 440/6 runs rich, too rich. My engine is stock except for the camshaft, due to the non-stock cam, I pull about 6 inches of vacuum at idle. (I would like more vacuum, but it is what it is.) I suspect I have an incorrect power valve. I read that divide the vacuum by 2, then step...

    What is the expected idle vacuum for a 440 six barrel? My car idles at 900 rpm, although the idle is rough. I'm showing 7 lbs vacuum at idle, the vacuum jumps to the 18 range as soon as I open the throttle. It momentarily goes over 20 when I release the throttle.
