Welcome to the forum!!! Have you tried doing a search? There have been several threads about swapping engines. But someone here should be able to help, just hang in there.

may sound like a dummy but how do ya search

One of the links under the big black line at the top of the page that says "search", that will take you to the page where you input what you are looking for.

yep went there nothing specific worried about the fuel system timming computer etc etc

So, are you saying the searched helped or it didn't? Because if not, there are very knowledgable people here, and a few GM techs, they will chime in when they can if you need more help.

Going to spend more time today checking out the seach links, I'll let ya know how I make out.
Tks
 

Having done a couple engine swaps in the past I think one of the best tips I can give you is to perform the swap so that the engine "feels" like it never left the other vehicle.  This will help you in troubleshooting and make your project go much smoother.  An engine swap can most easily be performed when it has been completely planned out and it also depends on what you have on hand to use.  By that I mean do you have a whole donor vehicle or just an engine and transmission or just and engine, having the entire donor vehicle makes it much easier to perform the swap so that engine still "feels" at home in the other vehicle.  I hope this makes sense and I have performed and consulted on a couple engine swaps and this is by far the biggest tip everybody has commented on.  Let me know if you have any specific questions.

A donor truck was an option that I was concidering but I'm always worried about wreaks unless you know the trucks owner and not too many low mileage trucks or wreaks around here. I'm out in the sticks 3 hrs from the nearest city, that's why I was thinking a create engine.
So far this is what I know
The transmission should bolt right up with no mods
Engine mounts the same
Rad and shourds should be the same
Alternator, steer pump and other accessories should bolt right up
Intake manifold and throttle body should be the same
Computer has to be chipped for 350
Wiring should be the same
Things I don't know
Is the Torque converter ok to use
Are the Engine sensors the same

I am not sure exactly what your project is.  Do you currently have a '97 with 5.0 liter and you want to just change it to a 5.7 liter?  If that is the case the swap should be fairly easy to do.  Like you say most every thing should bolt right up.  I wouldn't be think the torque converter would be much different between the two engines, probably both of them stall around 1000-1500 rpm.  As far as the computer goes I would just try to find another '97 truck with a 350 and use that computer.  If you need help locating one I can get one here locally and ship it to you.  Heads will be different on the 5.0 liter vs. the 5.7 but I don't think you are going to swap those anyway.

My 97 ext cab Chev 4x4 has a 5 liter engine with 195,000 km and it started to make engine noise last fall, the noise goes away after it warms up, I think it piston slap. I'm kinda worried about the engine because I tow a 5600 lb trailer in the summer and thought I'd upgrade to a newer 5.7 liter so it dosen't blow up on the road. The truck's in good shape and all, alittle rust but no big deal, I'm on a budget about $3 grand.
If I can use most of the 5 liter engine parts for the swap I might be able to save a few bucks.
I'm not sure about the ignition system will the 5 liter components work?
If the heads won't fit from 5 liter to 5.7 will I need new valve covers?
So any help here is welcomed
