Hi Grant, Thats a scarry feeling. I bought this car about 6 months ago and did have it running but never more than a fast idle. It actually idled fairly smooth and showed good oil pressure. I was checking things and the vacumm while around 20 lbs would rapidly jump from 19 to 21 so I knew somwthing was up. I thought a good valve adjustment would take care of it. When I pulled the covers and started to adjust I noticed the 7 intake wasn't moving and the rod was beside the rocker arm. I shut it off and thought I would just adjust it to where I could slip it over rhe rod. When I touched it it dropped out of site. The bottom piece was stuck in the lifter as it should be and I was able to lift the pcs out. Now I am putting it back together and pray there is no damage other than that.
When you buy an old car that has been setting you have kno idea what you have.
Have a good day and keep the rev's down a little.

If you were to switch plug wires on 5 and 7 it really
doesnt change alot so if you lost #7 it MAY still
idle fair but you would notice it at higher revs

Well, I replaced the push rods, adhusted the valves, Changed the oil and filter, and installed new plugs. I was really surprized how good this thing runs now. The vacumm is 19 and steady. The car starts easy and seems to have plenty of power. Now I get to go back to replacing the leaf springs with new ones. Thanks everyone for your help, especially rapidrobert for going out of his way to answer all of my questions.

Hi,
there's no offset on the 273 solid lifter rocker arms. The hydraulic type were all offset including the TA arms.

I didn't see any differance in the rockers, but sure wanted to make sure before this happened again. I didn't find any thing that would show me what caused it. All I can say is it sure runs good now.

probably just spun the heck out of it, over revved.
I never saw one break myself, usually it's the rocker arm that lets go right in the push rod cup.


I have mechanical Aptitude.
I can screw up anything.

As I said, I bought it from someone so have no idea how it was treated before. She sure sounds great now. I can't wait to get her on the road.

Yeah I was just tossing out my guess. Glad it was not too bad, and it's running good. Have fun with it.
