Most cam companies list gen 1 rpm ranges with their LT1 cams. The LT1 intake manifold drastically raises the actual needed rpm range. That cam is about 15degrees too big on the intake side and a cam with those lift numbers should be run with 1.6 rockers to raise the lift to a reasonable level.
Far as clearance concerns, PTV clearance should be no concern, you will however need new springs and hardware.
You might find a dyno graph of a cam that big peaking low enough to use with a stock shortblock LT1 BUT that would probably just show you the stock heads are choking it. Those of us running properly ported LT1 heads are spinning cams nearly 15degrees smaller all the way to 7000rpms and still making power there.
