Too bad the ATX mated up to ANYTHING automatically makes it an TURD!
I say rebuild the SVT with a 3L Engine using the SVT cams and sell everythign else. Throw in some aftermarket bucket seats (GOOD ONES!) like Sparco, Corbeau, or Momo, and sell the turd with an ATX. If you want speed nothing short of greasing up the ATX contour and pushing it down a mineshaft, will ever make it fast.
