Default Used engine- items to replace?

I am in the process of getting a new motor for my 1996 silverado from a member on here. In talks with him (or her?) the motor has about 160k and only has a small valve cover oil leak. I plan on keeping the truck, I doubt id actually ever sell it, so what should I replace on it before it actually goes into the truck?

I'm not sure I really want to break open a perfectly good motor to replace parts that haven't actually worn out yet, but at the same time I don't want to have to replace something major 5,000 miles after I put the motor in. So I was thinking maybe the intake gasket, and possibly timing chain, oil pump/ oil pan gasket? I plan on getting a set of shorty headers so the manifolds will be going away either way.

I have always wanted to build up the motor a bit, I have a tuned pcm from black bear customs, so would now be the time to instal a new cam?

I would rather not spend a hole ton of money on it since the truck is really just a PP and I don't have a ton of extra money to throw at it....but would it be worth it to throw a few extra bucks at it now?

If u have plans to do any thing to the motor now would be the time for the simple fact you don't have it in the truck

Master gasket kit and run it.

Those motors are easy enough to find. You are going to loose the rings or a valve before 190 anyway. Just toss it in and keep a eye out for a rebuilt one they are all over.

Like this thing for $1400. http://grandrapids.craigslist.org/ptd/3849796455.html

Tons of others out there if you look for them.

Do the rear main seal while you can look at it, not later and have to pull the trans to do it.

You do make a good point. I could build it way up over a longer time

But at the same time; I might as well build up this motor before I put it in, I wouldn't have to wait as long and I already have a different truck to drive in the mean time...I'm just a cheap ass and I don't really want to spend money I don't need to....unless it's a really good deal lol


..........this all being said, i'm probably going to end up just running the motor as is because I don't want to actually do the work lol I wanted to see what other opinions there were from the gl4x4 community, if it really is worth the time

If it is a vortec 350 put a intake gasket in it, they all go bad. Check the dist and dist gear for wear, another common problem. Make sure it doesnt have any busted exaust bolts stuck in the heads.
I wouldnt replace the rear main, they dont go bad unless the crank is going bad.
