R3W7 Assembly

The method I use is pretty simple...and it's the same as T&D mentions in this document. With the actual cam/lifters/valves, etc. in place I use a feeler gauge to maintain the lash then adjust the pushrod thread to the right length. Once that's determined, I send the pushrod(s) to the pushrod company and tell them to replicate it.

Note how in the T&D sheet it says to establish the initial thread on the adjuster at 1 thread down then never deviate more than one turn from there. It shows the need for an accurate length pushrod, at least with their setup.
