***320 rwhp AFTER heads and a Blower??? IEEEESH...that isn't all too good.
The heads were just new 99+heads i believe, and they weren't ported or anything. The guy was only making like 252rwhp without the heads/intake swap. I don't think they put a cam in it did they? I am not sure, it's been a while since I've read the article. But it was a HUGE gain over his previous heads/intake. Maybe not all that impressive on paper, but 252 rwhp vs. 323rwhp(I think) is a good gain.
