Even without SM he would win sadly.His chakra control is too damn good, he can use 1 handed rasengan's and odama rasengan,Futon Rasenshurikan and rasengan barrage all in base.
Restrict that and it's a lot closer... Still see Naruto taking it with some high diff due to Rasenshuriken (Would damage himself, but also grant him the win).
Sasuke's entire battle styel is based on sharingan, its like taking taijutsu off lee, ok maybe im exagerating but sasuke has nothing on naruto w/o sharingan, this is a roflstomp
