I did a quick search and read the first 12 pages here in this section but wasn't able to locate a DIY thread on the 4.3 Vortec removal and install.

Can anyone here please help show me the way to a thread or link that would have this info.....with pics?

 

For what year, make model?

 

I was also looking for a Do-It-Yourself thread on this same issue (I had no luck). I am currently in the proccess of swapping out my blown 1999 4.3L vortec with a 1996 4.3L vortec out of an Astro van. My "new" engine only has about 80,000 miles on it. The one that I am currently changing out had 138,000. I am no professional Mechanic. However, I do have a nice garage, witha prettybig set of tools (my old man happens to own a pawn shop)...that helps..haha...

I recieved my engine from the boneyard1week and 2 days ago. Ever since it arrived I have put multiple garage hours in (after my nine to fiver), and two weekends in a row. Most ofmy hourshave beenalone, but I did have 2 days of help.I would say that most of the work can be done by yourself, except when you must seperate the flywheel from the torque converter (an when you put the engine and tranny back together). I am finally on the downhill side of the swap. Mynew engine is in the blazer,the flywheen is connected to the torque converter, the exhaust is connected to headers, all electricalplugs, ground wires, tranny cooler lines, fuel lines, sensors are hooked up. All I have to do is get another set of hands to help me align and tighten the bolts around the tranmission housing and put the radiator back in. It has been quite the experience. I should be ready to try and start it by tonight or tomorrow. I have my fingers crossed, that when I turn the key it will start. If you have specific questions I might be able to help you out. I do plan on writing something up (with pics) and posting it on here when I complete everything.

 

wish I would have seen this sooner.
sounds like your well on your way.
When I did my swap I left the coil wire disconnected. I wanted to hear the engine crank over before i tried to start it. that way if something didnt sound right i wouldnt damage it.
