360 mystery breakdown

I had a feeling this was going to happen at some point; been running this 360 on the edge of detonation for so long it was bound to fail somehow. I'm at the point now where it's back in my garage and I've confirmed that it has a rod knock on #8 cylinder by doing the plug-wire pull test while it's running. I'm willing to bet one of the rod bolts failed because being the newbie I was back when I built this thing, I bought ARP rod bolts without knowing that the rods needed to be resized so I just reused the old factory ones :BangHead:

So I think I'm gonna at least pull the intake and heads with the engine in the car and then probably drop the pan to take a look in the crankcase before I pull the short block. My conundrum is that I used factory rods and crank but had them balanced with my KB 107 pistons. I would like to reuse as many parts as possible and put it back together without spending more than necessary, I guess that depends on the condition of everything else inside... I wouldn't be surprised if my pistons were chipped from all the pinging although it ran great and had little to no blowby with very little oil consumption.

It's probably safe to assume though that I should at least prepare for a full teardown...?
