If you are using like the PRW/mopar adjustable type you should have 2-4 threads of the adjuster showing below the rocker when you measure the pushrod (just go 3..) and different companies will tell you how to measure..
That's about where I was. Mike had recommended one full turn.
(always go smith brothers.. they are fast, they are one of the best.. and not that expensive) for mine..
I used Smith Bros. They have an almost infinite inventory of off the shelf pushrods that will ship same-day if you order early enough in the morning.
you measure the entire length of the measuring pushrod then subtract X amount for the cup (i think it was like .150) cause they actually want the number from the bottom of the pushrod to the inside of the cup, not the outer edge. If you did end to end you would be slightly long..
Are your pushrods ball/cup? Mine are ball/ball.
