Larry is right the 292 cam is also clearanced for the rods to travel past it. In 6 locations. You can also do this, I did with a grinder, did not get to use my favorite tool this time (sawzall).
If anyone looks in lets say the Competition cams catalog (online). You will see that a High Energy grind for either a 250 or 292 use the exact same specification for the lobes lift and duration. Where it gets different is when the cubic inch's of the engine come into play. As Larry and CNC said, a cam that seems big in a 250 will seem smaller in a 292. Back to work. Tom
