How much harder would it be to repower with the LS style? Do the LS engines use the same bellhousing bolt pattern, and the same engine mounts? Flywheel bolt patterns? A 5.3, 6.0, or 6.2 from a pickup might be an "interesting" upgrade if it's not to radical of a project.

Also, what specs of cam regrind would you recommend? What's the cost and where can you get the regrind done? Anybody whom you would recommend?
The bellhousing pattern is the same except for one bolt, the flywheels are different, engine mounts are different, Mike Jones can get you a good regrind.

A 5.3L can be bought for $500 or less. The larger ones cost a few grand.
