I just had my 460 done by a shop called Hartung Motor Exchange. They did a really good job.
The number is 245-7470. They're at 910 8th street West. If I remember right the guy's name is Norm. All the machine work and reassembly of my long block was $1490 with a 1 year warranty. I've put just over 2000 miles on my truck and I don't have any problems at all.......except it's THIRSTY! I might have to take Hoss to Gasoline-ics anonomous.
