Re: [Chrysler300] Freeze Plugs Continued - Help

Richard & group.

I experienced similar dead cylinder, just this week on a '62 383 engine. 
  I just finished installing the rockers on the engine which was 
original in the car and with unknown miles on it (either 33K or 133K 
miles per the cars odometer).  The car has set some 20 years. some 7 
years ago I I removed the pans, covers and rockers and cleaned the 
engine in and out and painted it.  I just got it started this last week 
after trying for days getting it to start.   When I put new (set I had 
on shelf for years) of Champion spark plugs in i finally got it started. 
  but it ran terrible with lots of smoke out the exhaust.   I ran a 
compression check of the cylinders and got readings of 155 psig average 
(cold) on 7 cylinders and zero on #7 ,   Thinking I had a hole in the 
piston, or stuck valve  I Put compressed air into the #7 and put my hand 
over the the oil filler hole and carburetor - air was coming through the 
carb.    I removed the valve cover and cranked over the engine and saw 
that the valves were opening and closing.  thinking I had a bad intake 
valve I removed the rocker arm  (preparing to remove the head) when I 
discovered  the #7 intake push rod was bent in an "S" and the top side 
of the lifter broken off.  I also observed that two of the Champion 
spark plugs were not firing (clean as new)
so I tested the resistance of the plugs, with my Fluke tester and got 
the following readings;

1,6 ohm,  0.6 ohm, 53.7 ohm.  0 ohm (no continuity),  5.7 ohm,  9,7 ohm, 
5.1 ohm,  3,2 ohm.  

I then pulled off my parts shelf a new set of Autolite Plugs and 
measured their resistance and got consistence readings of 5 ohms, 
plus/minus 1 ohm.

With the replaced push rod, lifter, and Autolite spark plugs I got the 
engine started and running like new  with the #7 cylinder now reading 
154 psig.  This proves to me, first hand, what I read  on the the Dodge 
Shelby news group site that the Champion plugs made the Dodge Shelby's 
run like  "crap"  when compared to Nepodenzia (spelling??) or some of 
the other quality Mfg. plugs.  

I suspect that the rod jumped out the the initially collapsed lifter (or 
I may not have seated the rod in the lifter - although I had checked 
each rod after tighten the rocker shaft

>I just finished doing a compression check on the 413 in the G. All cylinders measured between 130 to 135 lbs. except for cylinder #6 which measured ZERO. Didn't even get a twitch out of the needle on the compression gauge. I put my finger over the hole and didn't feel anything (forcing of air out or suction). It's like there is no piston.
