I agree on the upgrade to a 390
I changed out my 360 for a 390 and am very happy with the difference. I would love to have been able to go to the 460 but a 390 was a simple swap. That 30 extra inches make a huge change in the character of the truck.
I don't see getting rid of my 71, these older trucks get to be a part of you after a while.
