question for you big block swappers

[1FaastC10]

i've been tossing around the idea of something a little more practical for a toy. one of my initial thoughts was another 2wd C10, with a stock or very mild drivetrain, fully loaded, lowered, and cherried out. my buddy knew that i had been considering getting rid of my 86, and told me that he may be interested in getting rid of the 12,000 mi 454 he has that came out of a 77 C30 dually he bought for parts.

my question is, for those of you who have swapped in big blocks, is anyone running AC and/or factory cruise control? how hard was it to swap over from small block stuff?

i think if i do this, i'll look for a truck that is already loaded from the factory, and drive it with the stock drivetrain for a while. while i'm driving it, i'll get the body into decent condition, and make sure the brakes and suspension are up to par, then swap in the big block and a 4L80E. with the mild big block, and OD trans, it should make for an exciting little driver around town, and should get "reasonable" milage if i ever wanted to take it on the highway once in a while.
