If you want to do a 5.3/4L60E install, lots of pictures and info.

[Hart_Rod]

I know a lot of guys are doing these installs (or wanting to do one). I'm doing two of these myself, one in my 69 Suburban and one in my 67 CrewCab. I thought I would start a thread that would focus on trying to make this easier or at least take out some of the guess work. Maybe one of the moderators might tag it to the top, because it seems like it is asked daily. I know Shifty and a bunch of the other guys have done a lot of research on this and they should feel free to add as much information as they would like and I will go back and update the thread. Like I said, the goal is to have a thread that would allow most anyone do this installation.

I'm going to break the install up in parts.

1. Mechanical
a. Engine/Transmission (initial purchase and type)

4. Cooling system
