towing with a 4.8L?

Thanks Dan. I'm assuming he's towing a 4000+ lb. Impala SS ... remember those days well! My C5 is about 3200 without me (going to run IHRA Pure Stock) and the open trailer is 2000 so it will be just a touch over 5000 lbs. Also, just my wife and I in the truck and not a lot of extra "stuff" so I'm thinking it should be fine.
