My best advice: Leave the GTP alone so that it's his dependable daily driver. Go to ebay motors and type in "project car". Look for the lightest car you can find and afford that is rear wheel drive, one without a motor or trans. Now, find the biggest motor you can that is cheap in your area. It might be a 440 Chrysler or a 472 or 500 Cadillac or whatever. In many cases, it's better to buy the whole car and use what you can off it, then sell the rest of the sheet metal and glass to recoup some of your investment. If you've never done an engine swap, go to amazon.com and order some of the books on the subject (swap, swaps, swapping).

It should be easy to get into the 11's with such a car. You can run as quick as 11.50 at the drag strip without needing a roll bar. All you would need is a good Snell approved helmet and driveshaft loop.

Build a tow bar to tow the rod to the strip with the GTP. This kid does not need a car that will go 12's on the street anyway. It's a recipe for disaster in my opinion.
