Here is the story, every time I go over a bump or pot holes while flooring it I loose power and the car jerks rather violently. I really dont know any other way to explain it outside the way I just did. Does anyone have any ideas what may cause this or like I said is it just all in my mind. Thanks for the help.

Dark,

I'd start looking for poor connections at the ignition coil, pickup coil, HEI module, and make sure the distributor cap is secured in place. Those little hook/tabs can be a little less than a positive connection at times.

The rotor might also be bouncing around.

It's also possible that some of the engine ground straps and cables are loose and breaking connection on the washboards. The same could be true of nearly any electrical connector, including those at the ECM, EST, firewall bulkhead connectors, fuse panel, battery cables, starter and alternator - you get the picture.

Worst of all, it could be some component(s) working loose inside the ECM, making intermittent connection when the bumps are encountered.

If you notice other electrical systems losing power, like the lights flickering on bumps, it might narrow down the problem.

Maybe you're just breaking traction?
