[Sonic Blue 85]

I would agree with the GT40Ps and a GT40/Cobra intake try to skip the explorer intake it will work but is smaller. The lower on both intakes can be ported but only the upper on the Cobra. There use to be a few people around that made some respectable improvements by porting the upper and lower. Retarding the cam and adding the 1.7s with a good port job on a set of GT40Ps and properly tuned, a set of 3.73s or 4.10s and some desent suspension with a set of ET streets should get you into the 12s the more you work on perfecting the combination and improve your driving low 12s and even high 11s are possible. With out some kind of tuning device stick with a stock cam. The speed density systems use vacuum to determine load and will run rich if you install a cam that lowers the vacuum. Something to also look into is a Tweecer. The Tweecer is basicaly a chip that can be reflashed as many times as you like and will hold 5 up to 5 differnet tunes, one of them being stock. You can data log with it which makes tuning much easier, you buy the chip and then down load the softwhare free. There is a Tweecer forum and the ECC tuner forum that you can learn a lot about tuning on those two forums. If you get a Tweecer you can tune the car with any cam,head,intake,TB and short block combo without converting to MAF. If you get into tuning the stock EFI computers you will learn how much room for improvement there is with the stock calibration in the factory computers. There is so much you can do with a factory computer that the factory did not do. Like I said earlier with the parts availible today. You should be able to get the car into at least high 12s, with some work you should get at least some mid 12s. You could probly get some well into the 12s with a set of drag radials. Good luck.
