Thats why I posted this, all I've read since I've been here is that cams don't do much for our cars other than a cool lope. Cams that would make some serious power and torque without robbing the mid range is worth investigating. I can't remember if they mentioned springs or not, but I'm sure they would be needed with those kind of gains. 75 hp on ported heads would get us all so close to that elusive 400 hp all motor, of course that would be at the crank, but still. If we start out with 300 hp, pick up 75 with ported heads and cams, seems like you could get another 25 or so with headers, udp's, tune and intake. If someone would develope us a nice intake manifold to throw into the mix, we would be setting pretty. I still believe a 400 hp n/a 4.6 will be common place before long. Time will tell if I'm right I guess.
