Good Advice on 5.3 Swap Into Lifted 69 Longbox

[mi396ss]

I know there have been alot of posts on here about the 5.3L swap but very few have to do with swapping them into 4x4s. I'd like to talk to someone who has done this and has had good (or bad) experiences with the conversion and is willing to give good advice. I have a lifted 69 long box with 36" tires, 400 sb, and 4 speed trans. I just bought a 2000 z71 with a 5.3 in it that I want to put in the 69. The truck is totally complete so I have everything. I guess what I'd like to talk to someone about are things like fuel delivery, what tranny I can use, motor mounts, etc. I've read through alot of the posts here and there are many options and even more opinions so I'd like to talk to someone who has gone through it. Thanks, John.
