u have three "i need help" post. ur not asking for much are u. lol
if ur piston is rattling in ur block that is not good. could be brokin piston skirt, all ur rings broke but then u would have blow by. or ur piston pin came loose. ur timing could of been up to high and u was hearing pinging from todays crappy gas. do u know what kind of pistons are in it and what u had ur timing set at?
ur piston probably wasnt rattling.

To quote myself:
I'd recommend sticking to one thread if you can , to avoid confusion.

So it sounds like you think it's got a rod knock? Are you sure it's not a lifter?
If your uncle is experienced, did he hear it, and agree that that was the problem? Have you taken the oil pan off yet and checked the rod bearings?
It's hard to make good recommendations without more information.

I think whoever built it the first time was trying to save money,and now it's apart.
Do you know for sure that the piston were what you heard rattling?
Was there any difference in oil pressure or temperature before & after this happened?
Did you switch to 87 octane during any of this?
It's a little hard to troubleshoot without seeing it.
