Smith Brothers push rods

These are what I am installing in my 117" build.I wanted to address my valve train stability and they should be up to the task.
7/16 to 3/8 taper,.165 wall thickness. 3/8 threads cut into the chromoly rod ends.24 TPI.
And as part of the give and take aspect,these rods are 45 grams/each heavier than my Feuling .095 wall adjustables.
This is Not going to be a high mileage build and valvetrain life is being taken into consideration.They are going to be paired up with Wood lifters and S&S rollers on S&S 675 cams.

Very cool! Glad to see you doing this!

I ran mine with my smith tapered adjustables... They showed evidence of flexing north of 6500 rpms. They were making a weird noise as well thats hard to describe. Pulled them,measured them and smiths made a set of solids .120 wall for me in 1 day.
