Re: [Chrysler300] compression

[Mike Apfelbeck <moparmike@xxxx>]

Park,
I assume you had the throttle& choke blocked wide open when you did your 
test(that will make a difference), if the timing chain is worn, it will 
give some somewhat lower readings on an otherwise good engine. Try rocking 
the engine back and forth with the distributor cap off and see if there 
seems to be some lost motion between the crank and the distributor shaft.
