Motor time!!
Well after a couple of evenings my motor is out! Really wasn't a bad job at all. Biggest PITA was the fuel line! Now I have to see about either fixing this one or putting a used one in.
I am on a small budget, but would like to do a few things while it is out. I want to put the IH up pipes on for sure. If I end up rebuilding this motor I'll get a new HPOP as the current one is a used one I bought and does not seem to be very strong.
Does anyone know of an overhaul manual on the 7.3. If I could get a good manual I would feel a little more comfortable tearing this thing apart!!LOL!

Ya, when I looked at this house the garage sold me. So many houses I looked at were only 20' deep, but this one has 1/2 of the garage 35' deep. Only wish they had put a 8' door in, but if fits.
Thanks! Was not aware someone had posted the login info!!
That sounds like a good idea.

Got the heads pulled this morning and found one piston cracked all the way across. All the other pistons have small 1/4 to 1/2 long cracks. I am guessing the small cracks have been there for a long time and one finally made it all the way through.
Question for some of you. If the cylinders are not scored could I get away with just replace the pistons and rings.
Here is a picture of the completely cracked piston.
This picture is typical of all the other pistons, except this one has a crack starting on both sides.

Bored 30 over, new pistons, rings, bearings and a valve job would be better then a used engine. Comp valve springs and upgraded push rods when the valve job is done would be good. Upgraded head studs are another plus. May even be cheaper then good used engine and much better.
Edit: Forged Rods too.

Ouch thats a big crack! Mine had a few cracks but nothing close to that... lucky you dont have any major damage. My guess would be you could just hone it and slap new pistons in. Although a bore and hone should only be about 200 bucks... almost not worth all the time honing it yourself at that price.

Definitely need pistons!
Cylinders all look perfect. Is there any benefit to boring it out if the walls are in good shape already? I know it would be best to do a complete overhaul, but beings money is extremely tight I am wondering if I can get away with just replacing the pistons and rings. Probably should just wait until the funds let me do it right I suppose, but man I miss driving my pickup!!
I am assuming the initial piston damage was done a long time ago when I was running the superchip tuner on it and towing some obscenely heavy loads. The way all the pistons have small cracks they all got a little too warm at some time. I am paying for not having gauges.

That is what I am assuming, unless someone else has ideas.
