It won't come out with steel wool but it's a pretty small area. Would you guys run it or scrap it? Lm7.

Get a drill and a hone. Will probably take you 10min to clean up

Yep. My 4.8 I bought was fille with water from sitting outside when I took it apart. It had rust built up on the cylinder walls to the point where the motor wouldn't even spin over by hand. We took some emory cloth to it with WD40 and then honed it with the pistons down at the bottom of the stroke. Not ideal for sure, but I wasn't paying to build it at the time. It is making quite a bit of power on a turbo setup now, and it has shown no problems of slowing down. I'd just clean it up and roll

Word up. Is engines are awesome. Payed 300 for mine through gaskets and studs on, then boost.

I would take it outside, get some muriatic acid, soak a rag, lay it on the rust
After the rust is gone, hit a little with a hone or sand paper in a back and fourth motion, spray it with wd-40, let it eat
be warned though, the acid will rust stuff quick, so coat any bare metal with wd-40-crap gets in the air and does nasty stuff
My 6.0 was way worse that that, and its holding

I don't mean to be rude, but that looks bad to me. Short of a good honing, anything else you do will run but the rings will have a short life.
And the deck looks bad to me as well. How did you clean it? Sanding disc! In the photo it looks gouged between the bores

Looks like a hot mess to me. You have it down that far already drop it off at the machine shop and see if they can clean up the bore and deck.

Don't get me wrong, this would definitely be the better option if you have the time. I was a little nervous about doing it the way I did, but so far it has worked out.
