I am in the process of building an LS1 for my 1993 Nissan 240sx. Here is a list of relevant mods:

-TSP 228R cam
-TSP stock length push rods
-PRC stage 1.0 heads
-LS7 (I think) hydraulic lifters
-Stock LS1 rockers

I was wondering if there was some info out there as to how to set my valve lash on this engine. I know on a stock LS1 you can just torque everything to 22ft-lbs and call it good but I was wondering if I could get away with that here.

Thanks!

basically after zero lash, your rocker bolt needs to tighten up between 1\4 to 1 full turn.

Forgive my lack of understanding here but doesn't this article explain how to measure push rod length?

Pushrod length determines the preload. Technically op isn't setting lash, he needs to establish the correct preload since it is a hydraulic cam. Lash is used for a solid lifter.
