273 rocker push rods

Well I measure each rocker and came up with an oal of 7.266 average, or a cup to ball length of 7.108.
Krazykuda, you mentioned using the nut locking style of adjusters. how much do the affect push rod length?


It depends on the design of the push rod stud... Some have 'more ball' than others... (That's what she said.... :D )

It's the distance from the tip of the ball to the start of the threads that you need to watch...

Our pushrod ended up to be 7.064", see post #37 here and it also has pics so you can see the adjusting studs and nuts with the proper adjustment and 1 1/2 threads below the rocker arm...

I would estimate that the locking nut studs are about .050" - .060" longer than the 'regular' stud without a lock nut, and going from the difference between your measurements and ours...
