Buying a 360 shortblock?

So this is a odd story but few years back I had bought a 408 from a friend. He had thought it was a 408 but upon opening it it was just a 360. He gave me my money back and it has sat in my shop for 3-4 years. It is 60 over, has speedpro flat tops with 2 valve reliefs, cut crank, new bearings, oil pump, cam bearings etc

I can not for the life of me ID the rods. They are bushed rods, use arp bolt and nut(like stock rods have) and have SH829 on them?

Engine has a crap set of heads bolted on it to keep cylinders sealed up and no cam in it(have a summit stock cam with it..no use to me) I just looked and engine has almost no rust starting yet even though it had sat.

He had offered it to me for 250 bucks now just so he doesn't have to worry about getting it out of here. Not sure what to do. I don't really need it but any spare short block isn't a bad thing

I would pull it back apart to check bearing clearance and ring gap at the least and give everything a good cleaning.

So can someone help me id the rods if I get a picture tomorrow and I think for 250 can/t go wrong?
