I would say you can go a little faster, especially with 3.54 gears. I have a 5.5 head and a touring cam so my car makes peak power around 2400RPM which is ~55MPH, after that power drops off quickly. I like to cruise closer to 50, seems like everything is happier there, including me.

I wouldn't want to hold the engine above 2400-2500RPM for very long, that would be my cutoff due to the gravity and splash oiling system.
