So yesterday was a beautiful morning and I decided to take the car to work. Its about 44 miles to work.
I work near Rich in Watertown. Anyways about 15 mins into the ride my car lost power and was shaking and
knocking bad! Like someone just retarded the distributer a whole turn. The car did not over heat and no hoses were blown. And the car starts with no problems, its just when you excel. I am going to figure it out tonight. Just figured I'd throw it out there.

Thanks for any help or recommendations.

I think I figured it out, Vacuum leak! I'll check tonight when I get home!

Maybe the choke didn't open ?

I was looking at your new air cleaner and wondering if the coil could be arcing to the base plate?

Also if you haven't driven the car a lot, maybe a gummed up fuel filter? Make sure you are getting fuel.

No the coil is actually pretty good distance away. probably 1.5"/2" or so.

Ground problem when it gets warm? Could be another electrical problem?

I a similar event with my 67. It turned out that the ignition module was not getting 12+ volts due to a poor ground. Under a low voltage condition the car would lay down on power, misfire etc.. Something to consider....

Well what I was hoping does not seem to be. I now don't think its a vacuum leak but I am still hoping it is!
Tonight I will try to diagnose the problem and hopefully fix it for a car show this weekend. I will look at everything you guys have suggested and let you all know. Thanks for the help.

Well my season is over for my baby. Bringing it in my shop pulling the engine to get some MAJOR SURGERY! No power and I can hear my pistons slapping around pretty hard. Probably going to bring it to PK machine shop and hopefully will have it ready for next year. Kind of sucks but I've been wanting to rebuild it anyway.

Oh no! I hope they can pinpoint the cause.

Jason, piston slap, although not good, won't cause a significant performance issue. You might be able to fix the issue at hand and get a couple of months more before you rip it apart.

Down on power? Id say spun bearing..

I changed the plugs, cap and rotor, checked the oil (no metal in it) I am thinking of pulling the valve covers next.
Whatever it is it sounds absolutely horrible, barely any power and practically feels like it is going to shake itself apart.
Probably going to pull the valve covers tonight, start it up and take a look.

Is the sound up top? Or down low? A pipe can be used to listen. Up top you could have a bent push rod or two. Down low would mean spun rod bearing. And that`s bad!

I would think a spun bearing will cause lots of noise and will result in catastrophic failure but won't make it run bad. Is it running on all cylinders? And have you tried pulling one plug at a time at least to determine which cylinder is not working?


I'm just throwing things out there.

Yup, I've changed all the plugs, cap and rotor and there were some that were pretty bad but I've seen worse. I did not take off the valve covers yet though, that is next when I have time.

Just throwing it out there. Any chance you pulled the distributor and didn't get it back in its original spot? Or maybe crossed a plug wire when you installed the new cap? Cross wired plugs will sometime let an engine run but poorly.

if you have a compression tester hook it up to spark plug #1 with compression gauge removed. You just want the rubber tube hooked up. Pull the coil wire and crank the car slowly, when the hose hooked to #1 hisses loud it's coming up on #1 compression stroke. When that happens the distributor rotor will be pointing at (or slightly past) the #1 spot on the dist cap. Once your certain of #1 You can check the firing order. It's always best to find #1 yourself and not rely on the #1 location shown in the shop manual.

just a thought but worth a few minutes to check.

Nope all this happened and then I changed everything.
