I've driven a long wheel base 4.8/4L80E van towing a 30ft car trailer (full of stuff for moving... not a car) over two mountain ranges... it could have used a little more grunt, but it is more than enough for daily driving, and blew my late 70's 350 in my truck (a SWB 80 C10) out of the water as far as performance. The 6.0 would be better, because who doesn't like more power? But the 4.8 will be plenty if you're not racing.

This is what I am thinking as well. hopefully all I need is a rod and crank (maybe) and with the right gears it will be just fine for what I am going to be doing.
anyone with any experience with the vinci mega torque cams? info I have found says power range 1400-5600 and great power in a 4.8 -6.0
