GT40P's or Twisted Wedge?

The GT-40P heads are high velocity, good torque heads which offer significantly more power than stock E7TE's. The crate engine with the B303 or E303 cam is rated at 320hp. So no. A stage 1 GT-40P setup with the extra's is not optimistic at 320hp. Are low 12's with these heads realistic? In a full weight car and normal suspension mods, no. If you lose some weight and get some real good suspension and you have the rest of the combo? Yes.

If you have a car that's dynoing 290hp (240rwhp) with GT-40P's and all the rest with a 103.5 trap, it's broken. That's all there is to it. A stock fox with a killer driver can trap 100mph. So unless you feel like telling me all the mods you made were good for 35hp, I'd have to say something's wrong.

The iron-headed gt-40 crate 302 was rated at 280hp.

The aluminum-headed gt-40 crate 302 was rated at 320hp.

That is directly from Ford SVO. Get it right. I've mentioned it to you before.

My car is not "broken" and I'm certainly not a killer driver..... but I can hold my own. If you knew anything about racing at the track other than what you read on the internet you'd know that 103.5 trap is about right for 290 hp. Since you like to read so much on the net about racing take a look at the graph on the attached link. A 3200lb car needs 290hp to hit 105mph trap speeds. Looks about right to me considering my car weighs in around 3250 with me in it and I was shifting with the stock tach (we all know how accurate they are).

Quit reading the magazines articles and internet stories about all of these fantastic times being achieved by these killer drivers. Spend some time at the track and talk with people there about the results they're acheiving with their combos. The track is the real-world and you have yet to experience it.
