"Touch the Clouds LT5", an awesome find! After watching the Corvette Online video of Graham dynoing the Gen III LT5, this video showed up. THANK YOU Brad Reeder!?? A GM employee from the day perhaps?
Here is a snapshot of life in June 1988 for the engineering and development of the ZR-1! Later in the video is high speed testing. Watching this video brings back a little of the excitement when the ZR-1, "The King of the Hill", was about to command the automotive world stage.
