I have owned and appreciated a 1960 3/4T, 4 spd GMC 305 for over 50 years.
It has literally done every thing I have asked of it and done them well.
I never have asked it to cruise on the interstate at 70 MPH, however, and never would.
Your new truck has great potential for many years of satisfaction and reliable service, but it was not designed or built for speed.
