Why do I feel like I work more of my triceps when I work my chest?

I do a lot of dumbbell bench, sometimes barbell and after a set my triceps are the ones that are all swollen and my chest is barely at all. When I do barbell I use a wider grip so I know it's hitting my chest. My triceps are probably the strongest part of my upper body and my 1 rep max is 330lbs for bench, but I'm concerned because it seems like my chest is not growing. any thoughts? thanks.
