That may be a modern day replacement cam for the LT1 but the original had way more duration than that. It wa a long duration low lift solid cam. Not really a good cam for modern day engines. It needs a high compression piston and rpm to really work well.
Lookimg arond the duration at .050 is more like 242/252. Those are the numbers that are more like it.
