Light cylinder rust
This is one of the cylinders on my 390 that has been sitting on my engine stand for the last 8 years. This is the only "bad" cylinder for rust. What are my options for cleaning this up? Hone? Machine Shop? Other?
Appreciate any advice you can give, thanks.

Do the rings hang up when you push the piston over it? If it does, then it may be a problem. If it just goes over it like it's not there, then I'd just run it. It'd be gone within the first 30 seconds anyway.

Ya I think I would just hit it with a scotchbrite soft pad and use some light oil like 3 in1..so you can see it come loose!!
And if that doesnt smooth it out...A couple licks with cross hatch hone will...{ball hone} good luck!! Russ!! Keep us posted!!

Thanks for all the input guys. I should have just dropped it in and fired it up when I built it (95 or 96). But hey , life's funny sometimes.
It doesn't hang up on the rings at all when the engine is turned, so maybe I should just leave it. Oh well, bottom line is this engine is finally getting put in whether I like it or not. I've wimped around for too long, but now it's all about ACTION!
On another note, what about assembly lube after sitting that long? When I pulled the pushrods out to pull the manifold off, the dab of assembly lube was still there and felt good. Should I tear it down the rest of the way and relube everything or just assume it's all still good? I guess all I'd have to do is pull the timing cover off and the cam out do the cam bearings, then drop the oil pan for main and rod bearings. Seems like cheap insurance to me.

Yeah, go ahead and re-lube the cam lobes if you want. But the moly lube is there more so things dont get scratched on assembly. Honestly I would just throw it in and fire it up. It'll be fine. Remember to break in the cam properly and everything will be fine. It sounds like you've fussed with it enough.

Belt? .. check
Suspenders? .. check
Rope & twine? .. check
Okay, I'm ready to ... never mind.
It should be fine without doing anything exceptional. And I promise I'm not paranoid, except about those people out to get me!
I've had a bare block that had been hot-tanked, and then left to rust. Cleaned up the bore with a ball hone.. assembled... worked fine. The lube will not fall off.
You must've done a good job to have so little corrosion. Fire it up.
