Roadmarks,
You are right on. I have been saying the same for years. If it is in good shape, drive it like a truck and not museum piece. I have put many thousands of miles on this same setup. I never worried about RPM limits. The engine would take care of that for me.
I one drove 475 miles on the freeway in 6 hr and 45 mins in a stock 56 with a 235.
