Use stock 1970 340 rods in rebuild?

Like I said I got a whole box of rods pistons and pins for sale give me twenty bucks plus the shipping and they're yours there's a lot of weight there and I'll have to put them in a big plastic bin to ship I don't see any need in my future for them my next bill will be with a newer Magnum block
Thanks a lot but I have the 8 that were with the block and I'm pretty sure they're fine. Not really sure what I'll do yet anyway
