I dont know man its hard to beat porn.
Moderator participation, Some think moderation is bad, I think it gives the site an identity.
maybe a desk top dyno like program for both 5.0's and 4.6's.
A calculater that corrects ET's to sea level.
Tech articles for installing cams,gears etc...
Maybe you could substitute porn for a girl of the week feature or something.
BTW: I know you are not here for a post count. Neither am I, I was just giving you the standard newbie welcome. I threw out the bait and you didnt bite, I am impressed.
Later,
