Valve lash?
Need some help figuring out what valve lash to use on my engines. I have CBB talldeck, Crane 139651, Hydraulic roller lifters, Crane gold rockers. Have tried Crane homepage but I found 2 answers, 1/2-1 preload and on the camcard zero (0) lash with engine hot. As it is the first time with rollers and this cam I wonder whats the correct way to do it?

lashing out ...
I agree with Bobby D., once you find zero lash go 3/4 and lock down the poly lock, then torque the nut to 26-28 ft.lbs.

Having been through hell and back troubleshooting a recent rebuild problem. Many of the builders, shops and manufacturers have been recommending 1-1/2 turns. Is this too much? I've been informed that this is what a few Nascar teams are doing.
