From what I remember unless some of these things have changed it's a 427ci SBC built by Kenny Duttweiler, Twin T'netics 88mm turbos, Accell Gen7 DFI (used to be tuned by Job Spetter Jr.) and it runs in the Outlaw 10.5 class on the big 10.5"X33" 'W' tires. I believe they were trying a Bruno/Liberty 4spd setup but had some problems and decided to put a TH400 in it. The chassis was done by DMC Racing and there are some pics of it from a few years ago on their website~
