I ran between 340 and 360 for 18 months, nearly 40000 miles before it sh@t itself. I believe AlanG engine ran around 400 for a good while, and Fuzz had his running mid 400's for ages.
IMO though, at 350+ its a question of how long will it last? Every driver is different, some have 400+ and are gentle, some have 350 and beat the crap out of them!

401 bhp here, done 2 gearbox's but never had any engine trouble. It was mapped by Bob Rawle though which probably helped.

Well modified and with a1 mapping they can do 350, above that and you should probably start asking questions about how the car is used and longevity before proceeding further.
That said, Bob had no reservations about going for 400 with my MY99. But did advise that the gearbox and clutch would say cheerio before very long. The knack appears to be achieving the target output without exceeding the boost the internals can run (proba about 1,4-1.5 peak on a UK classic.
But it's really a "how long is a piece of string" type question.

Some will go pop at 240bhp, some more at 300bhp, 350 is pretty much your safe limit for cast pistons/rods, and I wouldnt want to do the same with a classic STI with those rods 
though you do get a few that seem to hold on quite well, you get a lot more that dont

Another thing to consider is how much power do you need relative to how much you can afford?
A classic with 320bhp+ is a very quick car (remember it only weighs around 1250KGs) it'll be more than enough for most. Sure, you can go higher, but can you stomach the costs to do it properly/if things go **** up?
