Good to hear. You've been very helpful, Ross. Thank you.

Driving in "H" for you 1956'ers or (^D) for us 1955'ers isn't very pleasant for me at my 7000 feet above sea level. Any naturally aspirated engine is down on torque by at least 23% up here, and lugging a 4600 pound Packard off the line with nothing but a torque converter is not much fun when you are missing that much torque.

There is no doubt that these cars have plenty of thrust once they are out on the open road. The Packard V8 is one heck of a low RPM slugger. There is a long and steep 65 mph highway grade near my house that climbs up to nearly 8000 feet. It's a good road test for engine power. My Packard has no trouble on it. I was really impressed the first time I did it. Even the most powerful cars feel that grade.
