Big Block Swap How-To

[69-350]

I've got a little request here... I guess I've got a 454 lined up that I am going to buy and shove into my 69. So I wanted to come along here and hopefully get a fairly clean, easy-to-read thread stuffed with good ideas, tips, etc to create a good little How-To thread for future reference by anybody hoping to swap a big block.

First off, I would like some information and maybe some tips on everything I need.
My '69 was an Inline-6 truck, somebody shoved a 350 in there, and now I want to convert that to a 454 (that thing's powertrain is moving up in the world, ain't it? ) which is from a 79 4WD Chevy.

-Starting with the engine, should I have to move the transmission forward any to be able to hook it up to the new big block? Will I have to modify the cab to fit the big block in there?
-Also, will my original 1969 4-Spd Tranny hook directly up to that 1979 454?
-What motor mounts should I go with?
-Anything else with bolting the engine in that I should know?

Next, comes non-engine parts, such as suspension/steering, etc.
-What do I need for steering parts?
-This 1979's 454 comes with Pwr Steering, how can I go about to converting this so it can work on my 69? (or removing it all together, is an option)
-Should I replace any stock Inline-6 suspension parts? Will the suspension sag too much?

After the basic installation, parts swapping, I guess comes wrapping up with the installation of a nice big block, including Wiring, Misc. things, and little odd jobs.
-What do I need to do for wiring? What do I need to modify for wiring?
-Anything else I need to do past the drop in, bolt in, wire in?
-What outside of the engine bay area needs to be modified? (including inside of the cab, etc)
-Anything else I missed or need to know about swapping in this Big Block pushing 454 cubic inches of Chevy fire-power?

All creative, productive, and helpful posts are more than welcome, and anyone who can give me and anyone else who reads this thread some help to install this 454 at least semi-professional (or semi-rednecked) is more than welcome to post their input. Thanks in advance!
