How much timing do you have? Stock cam car usually pull to about 6000-6200rpm before falling off, and by 6200-6400rpm start falling, if not earlier, depending on how well the exhaust is breathing and gearing.

Not to hijack, but taking your car to the rev limiter, when stock, doesnt necessarily increase your peak numbers because the power is dropping off by then, am i correct in assuming this?

Stock ls1 (with the stock cams) usually peak at 5.5k, so yours is perfectly normal.

+1, there was a stock one with 118K miles that peaked at 5300 or so. Graph is posted in my "high mileage dyno" question thread. Made 306whp though so dont knock it.
