I was making that comparison based on 1970 technology and what we had back then.
I really don't think there is anywhere near as much difference with what was being used for hydraulic lifters in the modern era.
My hydraulic roller cam/lifter equipped EFI LT-1 could rev to the moon with very moderate spring pressure. Maybe not the best comparison to a flat lifter cams but still hydraulic lifters...
