Erson cam specs??

That cam with 226 @ .050 probably has an operating range of about 1800-5500, possibly a bit more. Remember "small cam" doesn't mean "bad cam". That's an excellent street grind. Not a thing in the world wrong with it. Will be very easy on the valve train and probably run for a very long time with no trouble whatsoever. Comparing it to stock cams with duration @ .050 figures under 200, that's a sizeable cam. Just because a cam doesn't have 250 @ .050 doesn't mean it has no worth.
