If you are building an engine today (~2023), Professionals are not building Hydraulic FLat Tappet camshaft engines? Don't try?

So, I hotted up these tach/hour meters. The 350 vortec has 11,842 hours AND the gen7 BBC has 29685 hours. At 60 miles an hour for a comparison, IF it ran night and day, that one has 1,781,100 miles on it. So yeah it wore out the cam.
