Yep thats the plan there. Just need to get it!
Nice work man, getting it started is a huge step that shows all the work you did!

So here is what im dealing with on the exhaust. The driver side will be pretty straight forward. Just need a couple adapters.
The passenger side is tough one... Here is with a 90*
And a 45*
So im thinking either get a few mandral bends and cut and weld an "S" type piece together, or get the exhaust shop to bend me about a 60* piece and go from there.

Looking good, you guys doing these swaps are killing me....lol. I keep thinking of doing that to my 83...
Nice work,

I think it would be a REALLY easy swap if you had a pre electronic speedo and you werent concerned about keeping VSS.

Nice work,
Do it it's not that bad if you do your homework on it first.

Looks like your gonna have to mix and match some 90s and 45s to get it to work.
I thought these engines (actually, the ECM) want a VSS signal? Or they run better with it? Or something like that...

They dont "need" it. They just should have it to avoid possible stalling issues under hard breaking and stuff like that and legend goes that with the vss it allows the computer to access different timing tables and whatnot. Im running one so i should be good, but LOTS of guys out there arent and there stuff seems to run just fine. I think if i were to put one in one of my older trucks, i would give it a go without a vss first and see how it goes.
My thought was to get one of those adapters that goes on to speedo cable drive unit on the t-case that will send a VSS signal as well as drive the cable for the speedo. I just wondered how it would affect the ECM when in 4lo.
Maybe the ECM doesn't care as long as I use my 700R4.
I dunno, just thinking out loud here.

I think you would be just fine doing that. Like you said, as long as your using a non computer controlled trans. If i remember right, those speedo adapter things wont work with the computer unless you change the pulses per mile in the computer. So just keep that in mind.

Not that it matters much, but i got the exhaust figured out in my mind! Lets hope it works out as well as i think it will. Ultimately my home brew exhaust is not intended to be permanent but i think it will do me just fine for a couple hundred miles until i decide how i want the exhaust done at the shop.
You've done an excellent job keeping us up to date, and looks like you are almost driveable.
So, if you were to do it again, what things would you plan differently?
If/When i do this, it will be on a very abbreviated time table.

same here. I'm trying to find ways of doing as much as possible before yanking the old motor. I know some guys have their truck undrivable for years, but I'd rather not start down that road just yet.

Alot of what i would do differently would be financial stuff. I wouldnt have to pench pennies like i am now. One thing that i really wish would have been possible would be to get a COMPLETE motor. That would have been nice. And truthfully, i would rather have mounted the computer under the hood. Bit of extra work involved in mounting the computer under the dash. Also i would have gone with the dirty dingo mounts. Oh yea, that dang autometer oil pressure sending unit is 1/8th npt and the oil pressure sending unit is 1/4npt! Dont know why that pissed me off so bad but i think its just me mad at myself for not recognizing that the threads on the sending unit were 1/4npt... Had to get a 1/8th to 1/4 adapter. Oh well. Really cant think of alot i would do different other then that stuff. Unless i had more money! Cause then i would be doing all sorts of cool stuff like a/c and stuff. I really think that a person could get the swap done in two weekends without much trouble if they spent there time getting all their ducks in a row ahead of time. At that point it would be almost as simple as a plain old engine swap. Only stopping point would be stripping the old wiring out and incorperating the new wiring into it. I think the wiring alone would take the better part of a day. So i figure day one, pull motor, clean, change fuel pump. Day 2 wiring and drop new motor in. Day 3 hooking up all the wiring to the motor, exaust(?), assembly of the random stuff like air intake. Day 4 wrap up. Obviously thats assuming you had 9am-9pm days to work on it.

Just as a little addition here, straight from a GM brochure, the 2500 series trucks had 190hp compared to the 1500's having 210.
from a 2002 suburban review. Although i was pretty sure that only the 00-01 5.3 was 285hp and the 02-04 were 295hp.
From wiki
So i guess im going up a rated 95 hp.

What did you use for air intake?
Why the heck would you want to mount a sensitive electronic device in a harsh environment like under the hood? There is a reason no manufacturer does this and it's not because its simpler to mount inside the truck!!

lol they come under the hood from the factory.
Teck. The intake setup i have is supposedly off a hummer h2.
not sure yet how it will work out or if i will get one off a silverado, it just came with the motor so i figured i would try using it. Either way they seem to be a bit short to work on these trucks. If it is too short i plan on just taking some dimensions to the junk yard and searching until i find something that will work to extend the "snorkel tube" to the air box.
