I thought a stock LT1 was less than 260 rwhp (it is only 300 hp crank, right?) maybe you meant LT4.
But along these lines, I'm quite sure there is a solid 10% difference from dyno readings from shop A to shop B for a multitude of reasons. I thought my ZR-1 might have been 10 rwhp lower than I expected, but it got tested at 550 ft rather than sea level (and the engine was hot) and run in 3rd rather than 4th...could be 10 hp just in those testing conditions.
When in doubt, I like to back it up with 1/4 mile trap speeds as the true indicator. Before/After if really what the dyno is good for, you can always game the peak numbers.
