Caddy lifter preload
What are you guys that run these lifters running for preload? .100 or less?

They are pretty happy with anything like you would do with a stock LS7 lifter. We target anywhere from .050" to .130" depending on the application. If it's tight on PTV, we'll lean towards the light side, if that isn't a concern you can put a little more to them to reduce the room for squish. The lifter itself doesn't really care too much where in the preload range it is, as long as it's not bottomed out, or seeing lash when everything is warmed up and grown.
