Pushrod for hydraulic cam and 273 rocker arms
Here's the latest update:
We did get a measuring push rod and measured each 5 times to get a good average length. We ended up needing 7.058" from cup to ball.
We ordered a set, and they came. We measured them to be average of 7.064" +/- .005" from cup to ball and installed them....
We installed them today and have about an average of 1 1/2 threads below the rocker arm with the Comp Cams replacement lock studs/nuts for the rockers:
