Have any of yall ever floored your LT1 and have it almost hit a rev limiter of some sort? particularly around 60-75MPH? I was trying to pass a slow driver on the interstate today and floored the gas pedal, and all my car did was bust out and sound like it was hitting a rev limiter.... Stall wall? My transmission is fine, a lot of folks are telling me my trans is bout to give up the ghosts, but im showing no symptoms of loosing OD or any other gears. I have always run 93octane shell gasoline. I dont understand, it only does it around 60mph. From a dead stop, stalling it up on the converter it does fine and even flooring it from 50MPH its fine.
