1. what oil pan will mount on to my truck when you are going to run a 5.3 on a 93 silverado?
2. i currently have a gear box on my 93 when i swap to the newer motor what route should i take for power steering???

Welcome! Nice truck! There's a ton of very useful info on this forum.
Most of your swap has been discussed in one form or another and if
you run into any problems chances are someone knows the answer.

Does your truck lay full frame?
If your front crossmember is laying your going to have to swap the truck oil pan out for a shorter pan.
The f-body (camaro/ firebird) ls1 pan is perfect but they are pricey.
The one I plan on using is the cts-v pan, a bit cheaper and pretty accessible.
I did all the measurements and it should clear by an inch on my setup.
I'm also bodydropping my truck 3.5 inches so I have other clearance issues.
The muscle car pan (aka hummer h3) by my measurements will bearly hang below the crossmember.
The engine mounts have some to do with this though so you will have to check your clearance.
I'm fabricating my own mounts to get the engine as low in there as possible.

Good luck and post more pics!

Edit, the 5.3 pump and lines are nearly identical to your original power steering lines.
Just bend them a tad and bolt them in.

thanks for the info and no my truck does not lay complete frame it is not body drop ok ill check on the ls1 or the cts-v for oil pan thanks...
and also thanks for the power steering info

fabianss357 post a pic of your truck would like to see your set up? if you dnt mind

Lol mine is in about a million and one peices right now.
It was originally bagged to lay frame on 24s before I bought it
And now I'm doing the swap and bodydrop.
I have a thread I need to update around here somewhere.

And if your not laying frame, the truck pan might work ok,
if not you may be able to run the more economical muscle car oil pan kit.
Just FYI, all ls based engines share the same oil pan pattern.
The windage tray and oil pick up tube must be changed out to correspond with the pan your putting in.
Here's a great link for pans, including measurements.
