Establishing proper pushrod length
Installed a BTR Stage 2 cam, 225/238 625/238, and using the stock pushrods I'm getting a consistent .058-.060 of lifter preload after I find zero lash, and this is very repeatable. Sounds like these are the correct pushrods. Possible the BTR cams use the same base circle as stock???
Here is how I measured preload, after finding zero lash by gently running down the bolt with finger tips until bolt just stops, then torque bolt down. Don't think you can get more accurate that this:
