The issue is can you speed up a old truck, sure you can with enough time and money. The reality of the fact is that its not practical nor is it safe to expect a piece of machinery that was designed to operate in the 45-50 mph range to compete with the speeds that we have on the roads today. I operate a trucking company and we have Sterling trucks and these trucks are properly equipped and will go 65-70 mph on the freeways but still can be a handful at times with a truck maxed out at 33,000. As been said above, examine what you really want to do and then figure out a safe way to accomplish it.
Good Luck
