I ran a #10 in college for a while. Lots of street driving.
Took the car on a several hundred mile (one way trip) all was fine.
Was 30 miles away from Home on the way back when one of the #10 cams lobes
failed at cruise rpm. Got it towed home and removed the camshaft and lifters after
pulling the engine and cleaning the crap out of the engine. Cam bearings were fine.
Engine bearings looked good as the lobe failed and I immediately stopped on the road.
At that point I went to the 255/260 @.050 .540/.560 solid flat tappet camshaft and drove that for several years around town.
No more long trips. Comp (Roy and Mike Mckinney grind) cam. Johnson solid lifters.
