99 silvy ecsb 5.3 w/ no cats, bullet muffler, fram air filter, and the almighty hypercrapper. 1/4 tank, no tailgate and spare. 1st time ran right when I got there and ran 15.3@90 w/ 2.3 60ft. 2nd time got back in the lanes and it cooled a little and ran 15.2@89 w/ 2.2 60ft. 3rd time let it sit for a hour while I watched and ran 15.0X@90 w/ 2.2 60ft. heres the timeslip

 

That is a pretty good run for a pretty much stock ECSB!!

 

I forgot to mention that I have stock 3:42s w/ open locker.
