This TrailBlazer SS was so loud that we assumed it was all noise and no power. Boy, were we wrong. Martin Cox built the SS for his wife to drive, and she indeed hauls groceries with the SUV. Martin prefers to yank the 22s off the back of it, toss on some slicks, and abuse the 402-cid small-block to the tune of 11-second e.t.s. On Sunday, Martin ran a pass he says set the record for any LS-powered SS, an 11.07 at 125.3 mph.
