75' Quad Cab thoughts

[Anchorism]

So Ive just about got the quad cab ive been working towards and I would like to start getting opinions on what i have thought of doing. My initial plan is throw in the 454 ive got for ocassional driving duties. After that i will most likely start on the interior. I was looking at removing the seat setup it has currently has and build a custom center console. Also i would like to install the poly performance console shifter and get the one off the steering column. I am up in the air about carpet or rhino lining. I would prefer to go towards workability and durability. Now i am looking into converting to a 4wd rather than 2wd as i will be moving to Colorado come August. I plan on building the drivetrain for snow. Engine wise i am thinking about saving up for a 6.0 or an 8.1. Originally i was thinking diesel but with the frigid temps i would rather not have any gelling issues. Sounds rediculous but its been happening. Plus i believe driveability would be better with a FI than turbo diesel. Sooo any thoughts?? I will possibly be working on the truck this weekend a bit so i can try and get some more photos. Here is what ive got ATM.
