Hey,
I don't post here much at all, but I frequently lurk around searching for info.
I recently picked up an early 350 block that was cleaned up, decked and bored .030 over by the previous owner some 10 years ago. It sat in a warehouse since, slowly eating itself away.
So he doesn't remember exactly what was done, but it was clearly cleaned & machined, and a quick check with my calipers shows a 4.030" bore.
Since it was sitting in an uncontrolled environment for SO long, the surfaces started to rust and pit. I cleaned it up with some lube and scotchbrite pads, but some of it is bad. Please look at the following pics and let me know what you think.

Please pardon the messy garage!!
Should I send it to a machine shop for evaluation? Do you think honing will clean it up. I can borrow one if it will work? Or would opening to .040 or .060 be the better route??
A machinist friend of mind also insisted that each bore had to have been machined with a SPECIFIC piston in mind/in hand. Since I just have the block and no pistons, it should be re-machined or spec matched to whichever pistons I eventually purchase.
I'm an engineer by trade but a total newbie to engine design and building.
I'm also planning on chasing all the thread and going at all the passages with a wire brush, smoothening the oil return holes and slapping a coat of hemi orange on it. Maybe even some of that insulation paint under the timing cover and intake 'valley'.
Thanks,
Mike
