Cruising speed?

So mine is a 1972 C20 converted to dually (flatbed).
4.10 rear end
1997 nv4500
225/70/19.5 all around
5.3L fully rebuilt (stock internals)
Pontiac GTO intake and maf

My cruising speed is around 75mph and it got as high as 83 mph. What is yours? I am not looking for 140 mph responses, lol, but just kinda what speed ya'll comfortable in your LS powered truck.
