That only works with a solid cam, Walt. |

You may have perceived a difference but I can assure you that with hydraulic lifters, there is no change in either lift or duration by going either loose or tight on the preload. If there were then the hydraulic plunger wasn't doing its job. Some people do preload hydraulics on the loose side, which they claim makes them less sensitive to pump up, but I'd just as soon use an anti-pump up lifter that was designed to meter the oil flow to keep them from pumping up. I've never seen any proof that loose preload on a standard hydraulic does delay pump up. But I don't quible with those who like to run loose preload whether it works or not.
And if it did work that way with hydraulics (again, it does with solids), running tighter lash on the intake has the same, or nearly the same effect as retarding the cam. That being the intake closes later, not earlier as it would in advancing it. |
