Should I? 04 Yukon 5.3L into '66

[Chance66C10]

I love driving my 1966 C10 and want to make it a daily driver. I have a 2004 Yukon with a 5.3L LS engine that just sits in my driveway collecting dust. I have owned it since 20k miles and don't really want to to deal with having to sell it.

I got approval from my wife to pull the engine, transmission, and front seats (3 person w/ folding consol). I have started researching what all it would take, and this site has been extremely useful.

My 66 currently has a rebuilt 307 with a SM465 and runs good. It's a little rough driving it in Houston traffic though.

Am I crazy for trying to tackle this?

What all can I reuse from the Yukon?
