You want to gain 30lb? Great. You want to do it to get your dream body? Excellent. Now let's shift the time frame from 1 month to 12 months, and you might actually be closer to your dream body 12 months from now. Gain 30lb in 1 month, and you'll spend the next 12 months just trying to undo the damage (as oldie indicated, that's assuming you'll have 12 months after such a stint), and you'll end up more or less right back where you are now. Sorry to join in the buzz-kill parade, but unless your dream body is a fat body, there's not going to be any benefit to gaining more than 1lb/wk. For me personally, even 1lb/wk is too much to be worth while, and I'm currently about the same weight as you.
If you do it right, in the first year of progressive training and bulking, you might gain 20lb of muscle. Maybe. In the next year of progressive training and bulking, you might gain 10lb of muscle. Maybe. From there on out, you're looking at 3-5lb of new muscle mass per year of progressive training and bulking. So there's absolutely no point in gaining 30lb in under a year. Best case scenario you're looking at a couple years worth of training to get the body you're after. Gaining 30lb in a month won't fast-track those results: as oldie pointed out, if you're lucky it'll just make you 25lb fatter -- in reality it'll probably be even more fat gains than that, and the health consequences could seriously be devastating. Besides all that, if it doesn't kill you, it will turn you into a walking stretch mark, which probably won't complement your dream body.
