Wow - just picked up the vette and drove it 80 miles home to Orlando and it runs like a dream. Idles at a purr and tachs up to a nice steady growl. Gregg found a bunch of minor problems I wasn't even aware of and fixed them as well as doing the overall tune-up.
Did 70mph most the trip with occasional full-throttle romps (couldn't help it) and that old 283 just wants to keep winding up. Luvin it !
