If anything, the LSA is more reliable at its power rating than the LS9 is. In the story that GM provides on each engine, they mention the wide open throttle durability testing that each engine did. For the LS9 they say it went over 100 consecutive hours at wide open throttle. The LSA? Over 270 hours.
