13'* are very possible N/A, whether you can do it or not depends on how serious you want to get. ZZP'* GT ran 12.8'* IIRC WITHOUT the stroker. They blew up the stroker (due to another part failing in the engine, not anything related to the stroker parts themselves, IIRC the timing chain tensioner broke causing the timing chain to slip throwing some valves into pistons but I could be wrong) and so they threw in a regular L36 block with all the same heads/cam, etc... that they had on it with the stroker and ran it at MGM and turned 12'* with it. However, you have to personally see these cars to even come close to believing how gutted they are. Yes, their GT is actually a daily driven car like they say it is, Venessa drives the thing around everywhere, but when they get to the track, they pull all the seats out, the carpet, door panels, console, etc... They even pull off the cruise control module (which weighs like 1lb.) and stuff like that, then it gets skinnies and slicks and the whole works. Then at the end of the day they put it all back together and drive it home. Putting the engine from ZZP'* GT in your bonnie MIGHT get you into the 13.9'* or something like that full weight with just basic track prep, but I don't even know that for sure. And think of how modded this engine is...its got basically every mod you can get for the L36 on it, not to mention the torque convertor and gears that go along with it. For the money you would have to spend, its really not worth it IMO. Get forced induction or go home. :P
