I believe massive chests are attainable by benching alone. Several pros have done this, notably serge nubret and ken waller (who only decline benched). Something like cwick0 said is the trick. Serge used to do 3 sets of 15 bench at 225, when that was easy, he added a 4th set, when that was easy, a 5th. When 5 sets of 15 was easy, then he increased weight and went back down to 3 sets of 15. Then again, he increased to 5 sets as tolerated. Powerlifting is near-maximal training, to train muscle and CNS firing, etc. Bodybuilding is sub-maximal training, with progressive resistance, like that outlined above. I do something like this hypertrophy training, but to a lesser extent. I do 3sets of 6 with little rest, then advance to 3sets of 7 reps, then 3x8. When I can do 3x8 easy, I increase the weight, and go down to 3x6 again. Very simple, really. If you currently bench 275 for 3sets of 8, and sometime later do 3sets of 8 at 315lbs, your chest will have grown phenomenally. No other tricks, exercises, acupuncture, yoga or colonics will make a difference if this doesn't. Alot of people who talk about adequate strength but poor mass are frankly just not pushing enough weight. Beginner trainers 5'10" to 6'1" often can push 275 for 3 sets of 8 after a few weeks. If you are not doing at least this weight, then you really don't have enough strength to be massive. If you are already doing 315 or over for 3 sets of 8, then you probably have been over-focusing on power training (and quite successfully too!!) and higher reps will probably give you the look you seek. Hope this helps.
