I don’t see a oiling or a mechanical problem with idling on any cam for a long period. If I was picking up the kids as a normal daily thing, it wouldn’t be in a hot rod that uses a solid roller though. If I “Had to”, fine. As an everyday vehicle? The vehicle would certainly be a different vehicle though. Like a mundane grandma driver. That’s not to say it couldn’t be equipped with some go fast parts though! I’d just like an absolute easy driver with a smallish cam, nice idle quality and high vacuum along with a darn good heating and A/C system.
