Aaron Stapleton's Xtreme Street entry might have a Poncho outside but it is all Chevy under its skin. The engine was sourced from Steve Schmidt and boasts 525 ci with a Dart block. For induction, Stapleton added a single-stage fogger nitrous system, BMF 350 heads, and a Profiler intake with a Dominator carburetor. All told, the car has gone in the 7s in testing with a best of 8.0s in NMCA competition. Stapleton set high mph for the weekend with a 174 mph blast in the first round of eliminations. His best e.t. was an 8.07, which was on the same pass as his big mph blast.
