Default Bought a used 5.7 Rebuild it or Run it "as is"?

Hello need some advise and opinions please.
I bought a GOOD used 1989 tbi 350 on craigslist. The old man i bought it from claimed it ran well with no smoke an no knocks it just sat for 9 years and never got dropped into its project vehicle.

So do I run this thing as is? Or should I toss rings and bearings and a timing set at it? What would you do? This is not a race engine, just a temp daily driver for the next year or 2. I certainly couldn't afford machine work so you tell me, what would you do?

After sitting for 9 years I would definitely tear it apart and rebuild it. The car may have ran well at the time, but this was 9 years ago not the other day.

Wouldn't be surprised if the bores had rust on them and maybe even the rings be frozen in the bores. Bearings should be ok all this time, but up top not so much.

Thanks for the input! I know i'm not in the right section but this was the most active forum. The cylinders look okay and have the slightest ridge. The rod bearings looked good but one of the main bearings had some light scoring and the crank looked to have a few pits in that area but was smooth. Whats it typically cost to have a crank turned?

Not really a place to put this. It's not an LT1 engine either. So, it can stay.

What I would do is definitely have a machine shop go through it. Probably a solid $800-1000 or so for them to turn the crank, install new bearings, install new rings, hone the walls, and blueprint the shortblock.
