Okay saleenGTS we're talking about the GT40's not the GT40P's BIG difference there. Anyway you'll notice a big difference with the heads and intake swap. With that combo you're looking at probably mid-high 12's. If you can port them you'll go even faster. Plus you're probably getting a good deal on the heads so a set of aluminum heads is probably gonna run you atleast $600 dollars more. Ohh and saleen the 93 cobra came with gt40's not gt40p's. Ohh and the trophy stock guys are running in 11's and the factory stock guys and in 12's and drag radials. I would say the GT40's or the GT40P's are a great head. Look at the flow numbers. They're a very good N\A head too. Oh and I bet I can get 30 horses out of my P's with a port job. Just for kicks I'll tell you guys this my car Bone stock ran 15.3 @ 90-91 MPH. With underdrives and cold air it ran 14.9 @ 92 MPH. Now with the mods in my sig. and NO port work look what it runs.
I figure I'm going to port the heads and lower intake and then we'll see what it runs. Oh and those passes we're on BFG drag radials no slicks.
