My LT-1 engine has basically the same ring package many bracket engines would have. It has a roller cam so there is no worries about lifter or cam wear. Other than possibly installing some new valve springs and checking over the rockers and pivots there is no reason an engine can't run as many laps as Bob and Jim say. I have built bracket engines that went 300- 400 runs and still looked fine inside and they had flat tappet cams, more compression and saw the same rpm levels.
