Trans question is it worth building a 60e or should I just swap to a 80e? Next, the truck in question is a 04 1500 rcsb step side auto with a 4.8 and a 60e... what would I have to change on the truck to swap transmissions? Truck won't be over 500 tire... thanks in advance

In the truck there is tons of room for the 4L80, many came with that transmission. With that being said, what is the plans for the truck? Just a N/A set up or boost? At that level your 4l60 will be straining, but it could be build to handle it. The 4L80 will hold the power without modifications, but then add cost for a converter. Plus tuning....
I have the same truck as you and contemplating throwing this LQ4 I just picked up in there and run the 4L60 till it blows or I come across a 4l80 on the cheap.

In my opinion if you still have the stock 10 bolt and plan on keeping it, there really is no point in having an 80e. If the 10 bolt is alive, the 60e will live too.

The 80E is heavier. I just did the swap in my Nova.
A majority of the weight is the giant torque converter. I went with a 245mm which is a lot smaller and probably 15lbs lighter.
On the 10blt rear, I've been punishing my 8.5" 10 bolt for 16 years now.
Slicks and drag radials with a 8" treemaster that hard hits and flashed to 5k dead hooking at the track.
Stock 45yr old axles and all.

Looks like the only downsides to the 80e are weight and a slight power loss running the bigger trans. you wouldn't ever have to worry about it again really.

Honestly, It feels the same as the t350 it replaced.
Gear ratios are only .04 off from the 350.
I haven't run it yet but the 5C converter hits hard but a smidge too tight at idle for my cam. 262/269 @ .050", .630 net lift
I "may" send it back to be loosened up a smidge at idle.
If that's possible.
