Haven’t made it to the track yet, but with hopes of getting there this season I took the Satellite to the local chassis dyno to get WOT fueling dialed in. The ST-21 440 with stealth heads laid down 479 RWHP and 492 ft lbs of torque. A friends car makes 457 to the tires and runs 10.60s @ 3300 lbs so the dyno doesn’t appear to be too “happy.” With 453 ft lbs at 3300 RPM its no wonder the car feels like an animal mid range. I will update when I have a time slip to back up the dyno results (or a time slip that doesn’t). I think the old ST-21 made quite an impression on the dyno owner.
