Despite our efforts with the springs and rockers, the power peak was only 228 hp, but at least now it was flowing in a proper curve. It was particularly frustrating, considering the extra valve lift provided by the roller rockers should have done something. However, during this round of testing, Westech's Tom Habrzyk could sense that the torque converter was slipping even above its reported 3,000-rpm stall speed. Using a programmable feature of the Superflow chassis dyno, he tested his suspicions by accelerating the engine while limiting wheel speed. We managed to get just shy of 4,000 rpm before the engine was being held back by the driveline-our converter was flawed. We'll be removing it for further testing with B&M soon to see what went wrong.
