To OP- you don't say how fast the ls is. Most any big block a body "should" be able to whip up an ls camaro at the strip. Some can't but the ls tunes itself and the old iron doesn't. The z11s a quicker car but none of them even with some mods should be insurmountable at the drag strip. That being said if you want the whole package buy one. It will do everything the same and you'll disappear in any crowd.
