I think the issue with duplicates or the same topics over and over is that without them, no conversations would actually exist. There really isn't any topic on stangnet that hasn't been covered, so if everyone searched and found their answer there would be nothing for us to read. It's a catch 22, we want people to search, but if they do and revive an old thread, people bust their balls, if they find it and move on, there is no discussion and if they don't search and make a post sometimes their topic gets treated with no respect.
Bottom line, the site needs newbs to ask common questions to survive.
There are many times where I write up a response to a topic, then don't post it. Sometimes it's just better to say nothing at all.
As for the original topic here, 350rwhp is possible, I've seen it with afr 165's. It takes all high end parts, quality installation and you will give up some power down low. While I like gt40x heads, it's likely not happening with them.
Well considering im at 340 hp not sure if its crank or wheels the laptop says 340 hp and 340 torque and its got trick flow heads i believe trick flow cam trick flow intake and i believe some more im missing
