yes I did. just a little. how much are stock GTs supposed to weigh? some dude on another forum says the 99+ GTs weigh 3250. BTW, the 3150 is w/o me (3310). My friends 96 Cobra (no weight reduction) came in at 3320 w/o him. on my car I took out a/c, powersteering, sway bar, foglights/brackets, aluminum heads, fiberglass hood, alum d/s, removed dogbone. i woulda thought the car would have come in lighter. the 3150 is with about 1/3 tank. only weight adding mod was subframs (16lbs).tmoss said:I notice you put your stang on a diet - 3,150# GT?

Either traction was really bad which is either due to the track or your suspension being wrong. You don't know how to drive (no offence, we all have to learn, or something is wrong with your engine. Whatever is wrong, needs to be fixed first.
ET's are dominated by traction, then comes driver's ablility, then power comes third. With slicks and a full drag suspension, properly working engine, and the know how to use it, you could probally touch the 12's with your current engine setup.
You could look into some GT40/Explorer heads and intake first, you could save some money but they don't flow stock what thumper's or TMOSS's flow, and unless the heads are near new, they probally need a rebuild. One reason Thumper heads are a good value is they are completly rebuilt down the the valve job, plus the porting, it's a good deal. When you do get new heads, I recomend highly double valve springs, it makes a really big difference high rpm's and/or with a biger cam. The only thing, Iron heads weight a lot more, you would save 50lbs by going with an aluminun head. Which brings me to the next point...
...Another way to get your ET's down is to reduce weight and drag. As a general rule which proves to be mostly accurate, for every 100lbs of weight reduction equals a tenth off the ET, and a few lbs here and there adds up, and thenth reductions adds up. Also weight placement, more weight to be shifted to the rear, such as the battery, the better. The A/C, Smog, and P/S add drag and weight in the worse places.
