Oh he could finish for sure, but I am pretty confident he would get punted into the woods on more than one occasion by a faster competitor that is actually in the race and too impatient for a place to pass under the assumption that he is going to move out of the way quick enough. KoH is much different animal than racing through the woods on the east coast. I would say it is more like a 2 hr trainwreck with some bumper cars thrown in. Sounds fun, but if you are the underpowered and lighter car, I doubt you would try it more than once.
Not to mention the nearly $1000 entry fee to race 4400...
