Ideal lifter preload for 455
What's the ideal preload measurement for a 1968 455. Comp Cam OEM replacement rockers and lifters. A mild cam has been added as well. I'm getting .0269" currently but I'm not sure if it should be a little higher.

I think up to about .050" is OK. The hydraulic lifters will adjust and take up the slack to about that amount, so at 0.027" you are within the acceptable range.
